How do i know which version of nexus one i have?

Hey there,
I recently had a htc desire, i loved it. However, i will be living in panama for a while, and it wouldnt be so sweet to only have edge as they run 3g on the 850 band.
reading on this page there seems to be 2 versions of the nexus one. one with quad band and one with tri band..
http://en.wikipedia.org/wiki/Nexus_One
Is there a way to know what is in my phone if i am holding one i am potentially buying?
It seems the developer version on sale now is tri band sadly.. so i cannot buy a new one..

They're both quad band GSM for voice and data up to Edge. The difference is for 3G data. AT&T and T-Mobile use different 3G frequencies.

Pop in your sim card and see if it connects to 3g

Hehe, i would, if i could. i am currently in sweden, and here the T-mobile would 3g connect..
Is there for sure NO WAY to check this in the firmware somehow?
If its tmobile or att version of nexus one..

Easier to just copy and paste the info then have the OP go to another site.
Pull the battery and look for the PB # which is located just below the IMEI, S/N, and P/N #’s. You should see one of two PB numbers:
PB99110: 850 MHz, 1900 MHz, and 2100 MHz such as AT&T in the US and Rogers Wireless in Canada
PB99100: 900 MHz, AWS, 1700 and 2100 MHz such as T-Mobile US and Vodafone in Europe

At&t + T-Mobile Merger Hurts Potential US G2x Buyers

Hi alls, I wish I had better news to bring. The good news is, as expected, the 2X runs stock Froyo.
Now the kicker: as you are all probably aware, At&t has gobbled up T-mobile. This means that when the transition is complete (expected a year to 18 months from now) At&t will drop T-Mobile's 3G bands to EDGE.
It may not affect some owners but for me, I usually keep a device until a big hardware refresh comes about- like a quad-core chip. I'm skipping the 2x for the Galaxy II or the Optimus 3D. I was on the verge of owning this...

Luckily the normal 2X do support UMTS 1900 (one of the 3G bands AT&T use), that's why I am consider buying it off contract from other place and use it on AT&T

Let me understand: do you mean the non-US version of the 2x, the off-contract US retail model, or both? Thanks!

It's been reported that the G2x will support T-Mo *and* AT&T bands:
http://www.anandtech.com/show/4231/lg-optimus-2x-coming-to-usa-as-tmobile-g2x-
UMTS/HSDPA/HSUPA Support 1700 / 2100 (AWS) / 1900 / 850 MHz
So you can rest assured that T&A-Mobile will support the bands on your phone right through to the bitter end of HSPA over AWS, right?

Ha! I was spying Engaget & Giz all afternoon yesterday & the announcement was made @ Anand...! Thanks for the heads up!

at&t hasn't officially bought T-Mobile yet -_-
An acquisition of this magnitude might not even be legal, it has to be approved by the FCC and the DOJ

Just checked the specs on this new phone on the T-Mobile spec sheet that was posted on T-MO News ad and that device supports both T-Mobile and AT&T's 3G Networks. I had to recheck it over 10 times during the day in case it was a miss print and they are still posted.
Has anyone else found any news that is different???

Yes, this says different. (Dang it, I can't post links. Search on Engadget.com for "T-Mobile G2x lacks quadband HSPA+, shatters dreams")
That said, I'm still curious to find out if anybody else has tried the the 2X or the G2x on AT&T yet. I'm not smart enough to understand what the lack of 850 3G means. Is that an upload speed? So would I be able to download zippily on the 2100 Mhz band but my upload would take forever?

Further adding:
I'm interested in potentially buying the Optimus 2X (900/1900/2100 UMTS) not the G2x (1700/2100 UMTS). Anybody able to explain why the 2X may not work with AT&T, or share experience with it working?

The 2x will give you 3G on only the 1900 band with At&t, and not on the 850 band. So your 3G coverage will be worse than phones designed for the carrier. It will not get 3G on T-mobile.
You may as well just wait for the "Thrill 4G".

what are the speed test for this phone on tmobile?
and so if it dosent get 3g will it be getting edge?

Just in case someone finds this thread again, the G2X DOES NOT support *any* AT&T 3G frequencies:
http://www.phonedog.com/2011/04/27/...-quad-band-hspa-plus-won-t-work-with-at-t-3g/
It was a screw-up by T-Mobile to say it did.

Question before buying 02X

Hello everyone what is difference between this or T-Mobile version? Are they same I wana use it on wind/mobilicity in Canada wana know if both have 1700 and 2100 3g band. Cause T-Mobile phones work on wind/mobilicity if they are unlocked if I had to buy one which should I get? Which is better and y? Thanks

I think Tmobile G2xworks on wind/mobilicity
The Optimus 2x (O2x) does not work with wind/mobilicty according to this:
(Voice yes/data no)
LG P990 Optimus 2X
2G Network: GSM 850 / 900 / 1800 / 1900
3G Network: HSDPA 900 / 1900/ 2100
As for the difference, I assume only the brand logo on the screen or maybe some Tmobile apps.
-----------------------------------------------------------
I m too looking to waiting to get this into Canada.
However I'm worry about the freeze and otherse problem with this phone.
I'm holding it out until they have a *offical* fix and confirm it is not a hardware problem.
I have all the time untill SGS2 drops to around the price of this phone =)!
Plus it seems like the Motorola Atrix have reboot issue too..
My guess is a problem with the tegra 2 problem with software.. who knows...
*Edit* notice you're from Vancouver, how is mobilicity/wind service there?
Heard reception are crap =/

Mobilicity is awesome but wind service is crap. 10$ for unlimited data and mobilicity towers are built and maintain by Ericsson. Call quality is very good and clear. Even mobilesyrup.com said it. Ya also wanted sgs2 but no 1700 and 2100 band. I don't believe the random shutdown problem till I buy the phone.

O2X P990h (850mhz UMTS)

Hi guys,
I've searched the O2X forum regarding 850mhz UMTS (HSPA) and found nothing so far. Does anyone here have the O2X P990h model which supports the 850mhz UMTS band? The only thing I can find is that the G2X supports 850 but has the model number P999.
I'm currently tossing up between the Atrix and O2X (I use the Australian NextG network btw). The locked bootloader on the Atrix sucks and coming from a S-Off'ed Desire I really want custom roms etc., but the O2X doesn't have 850mhz support which is a must for me, at least until now.
Since then I've stumbled onto these:
http://www.mobicity.com.au/lg-optimus-2x-nextg.html
They appear to be in a lot of other online shops as well, has anyone actually got one and can confirm normal O2X mods/roms work on the P990H?

Hi, i get 'h' on mine above the signal bars which i am guessing is hspa. (I'm in the UK on orange.) Or am I getting confused with something different?
Sorry if i am talking about something different.
Sent from my LG-P990 using XDA App

This is on czech LG site for O2X:
2G network: GSM 850/900/1800/1900 MHz
3G network: UMTS 900/1900/2100, HSDPA 7,2Mbps / HSUPA 5,7 Mbps
so i guess 850Mhz for UMTS is really not supported, at least not on EU model (but i doubt the specs will be different elsewhere on P990)

Actually he's talking about one listed as "LG P990H Optimus 2x 850/1900 "
It's on negrielectronics web site as well as a few others... but it seems impossible to find out any information on it. I myself am also interested..

No, completely different. The standard Optimus model number is P990. There is a 2nd model called the P990H which has 850mhz UMTS support (apparently at least).
So nobody has ever bought or used one of these phones?

where do you see a 850 umts version ?

Fido's LG P990hn is an 3g 850/1900/2100 phone. I'm curious that is it able to flash a p990's third party rom or not.

Don't take this as a definitive answer, but yes, it should be.
As you can see from the included screenshot, the ROM itself (via Hidden menu) lets you select 850 bands for both GSM and WCDMA, even though the radio doesn't support WCDMA-850 on the regular P990, which the screenshot is from. (This is from the new official Gingerbread, but it was the same on Froyo.)
You may run into other problems of course, like the ROM not liking your baseband, which is the one thing you probably shouldn't replace with stuff from the P990.
As stated, I cannot say for sure, but I think you can try without damaging your phone. (Or get someone else to try it on theirs ;-)) Which is my way of saying you probably should get a second opinion. And a third.

Cant you just get a G2X? Theyre 850 i think. Or you could join the dark side and use optus

Just saw this thread and wanted to clarify for anyone else who might stumble upon it.
P990HN from Fido does support 850Mhz and also works with all the custom roms/kernels for P990

I'm brazilian.
In Brazil, UMTS is 850/2100mhz
(990h model)

here in mexico 850 its the 3g band, the 8xxx baseband + canadian ril makes the phone p990h, but the radio its not capable on p990 celphone, you can just load miui or cm7 and load the 8xxx baseband and the canadian ril then you can upgrade your phone

I have the LG Optumus 2x - P990.
This phone has a software lock on the UMTS 850Mhz Band.
Does anyone know how to root this phone and unlock it?
My phone will sometimes connect to 3G here in Canada, but then it reverts back to Edge Network. If I turn my phone Off/ON, it will usually connect to 3G then after a few mintues goes to Edge. Certian parts of the city I'm in will connect to 3G at all times, it's very strange.

I did not know (and still confused) about what I was doing when I flashed my Fido LG P990hN with T-mobile CyanogenMod7. I can operate on Rogers network, but its not stable. Im new to this so I don't know what questions to ask - I just keep reading forums and help files. Michael

I have the P990h model bring from Spain, and in the box says that works with 850/1900/2100 WCDMA, and all the roms from P990 works normally, right now im on CM7

ok guys, here what I found.
I started separate thread in Q&A section:
http://forum.xda-developers.com/showthread.php?t=1521105
I'm in Ontario, Canada on Rogers. Got LG o2x from buddy who bought it in Europe. Then my mystery started. At home I was getting 3G and H, but at work (about 50km away) was getting only EDGE. But buddy with iPhone had 3G all the time. I got suspicios. Tried everything - flashing different ROMs, RILs, BBs... Same sh...it.
Then, my another buddy bought used LG 3D (Thrill) which was sold by Rogers (i.e. official Canadian edition) and asked me to root it. I did and tested - he had 4G (same as H, I guess) all the time. WTF!!!
So quest continues...
I found hidden menu in both phones. There I could force phone to use exact band I wanted. And mystery was solved...
So I forced:
GSM850 - my o2x got Edge; buddies: 3D Edge (the same)
GSM1900 (GSM PCS on phone) - my o2x: G; buddies: G
WCDMA1900 (UMTS_Band_II) - my o2x: H; buddies: 4G
and now...
WCDMA850 (UMTS_Band_V) - my o2x: NOTHING; buddies: 4G
So I made the conclusion that European o2x has WCDMA850 band disabled somehow. It explaines why I have H at home (big city where H is on WCDMA1900) and only Edge at work (small town and H is on WCDMA850).
Now I'm trying to find out if it's possible to unlock/enable WCDMA850 band on this phone. I read that Samsung has hidden menu where you can select bands you want to use.
Does somebody have and idea if there is something like that in LG?
Thanks!!!

There is, but it won't do you much good, as this is, to my knowledge, a hardware limitation. The P990 can not use the 850Mhz band, the P990h and P990hN can.
If you still want to try you'll find band selection in the hidden menu. Dial 1809#*990#, select Modem Setting/Band selection.

That's exactly what I did - went into hidden menu and selected each band one by one and then checked status in Engineering Mode of Modem Settings.
Now I have next idea: all this experiment I did while having "canadian" baseband 823. And i had WCDMA850 line in Band selection (but it didn't work).
Now I'm wondering if I still have WCDMA850 entry if I put "european" baseband 725. This will be my next step tonight. Because if I have WCDMA850 in 725 bb then I would assume that phone CAN handle it but it's disabled somehow.
What do you think?
I just thought that for manufacture like LG is easier to make just one universal phone and then limit available bands using software (or firmware)...
Thanks for ideas!!!

You'll find the (non-functioning) 850 band on European basebands as well.
I'm no electronics engineer, but I think there's more involved in supporting a specific frequency than just the baseband. (I think each frequency needs some kind of dedicated amplifier among other things.) The chip itself is capable of supporting 850 I think, but not the rest of the "supporting" electronics. I may be completely wrong though.
Basically the P990h is the revision which enables the 850 band. I think trying to get it to work on the regular P990 is futile, but you're of course free to try anything you want.

If I remember rightly, in the O2X review by Aandtech, they say that the 850 option is there in software but not there in hardware (on European version). So even though you can select it, it won't work. (At least that's according to the initial review)

vivid in australia

I just sold my HTC inspire to get a vivid..
In Australia our 3g is 850 MHz and LTE is 1800 MHz...
If I buy an att vivid, will I be able to access these frequencies? My current phone is the att inspire.
There is a leaked pic of an Australian vivid on my carrier... Can anyone tell if its the same model as att one??
I don't wanna buy the wrong model....
Here is the pic..
http://m.cnet.com.au/htc-holiday-to-be-first-telstra-4g-smartphone-339323146.htm?redir=1

You will get the 3g speed but not LTE. AT&T LTE is 700MHz and the Vivid radio only supports the 700Mhz frequency.

Really? What are the numbers shown in these specs?

Is.there a model which will work in my area?

Don't bother getting one from here; looks like Telstra uses a very unique LTE band. 1800 means 1800, not 1700, so the Bell Raider won't work. Just wait for it when it comes out. The leaked ROM notes that it's to be called the "Velocity 4G", so keep an eye out for it instead of trying to fish on the international market.
LTE for USB dongles is using the same LTE as the mobile phones. It's on its way. It was like that on Verizon too, with the dongles first, then the rollout of phones.
@Pirate: Has HTC released an unbranded Raider? I didn't even know that existed already.
