I read that the official release of the S730 for the US will be 3G quad band.
I have a S730 thats is only for 2100. Will be the implementation of the other frequencies be software or hardware based ?
If it's SW would it be possible for my phone to work in quad band ?
Any ideas ?
If they included the radio for the other frequencies than a software flash should make it work, but I doubt they put the radios in for our frequencies here. I would be interested in knowing as well, but we shall see as the time gets closer
This was linked in another post. So their choices are clear, hopefully they chose to use the chip that supports all the freqs; but I doubt it, since the model IDs are different: WING220 (the EU version we all have) and the WING200 (the North American model).
Now let's see someone get the TV out working.
Seriously, we will see if writing NV item 0148 can also fix this issue.

As many of you may have already noticed, many of the Diamond's spec sheets say that the device's radio is capable of operating in all bands. Official word is that the device is tri-band (America or Europe). Is this limitation based on the settings for the rom or radio.
In other words, is it try or quad physicaly? And if it is, is somebody going to release a cab to enable it?

The chipset is capable of using other bands, but there is no antenna for these other bands. I am about 80% sure that in that case calibration data for the other bands will be missing in the Radio, and those bands will therefore be disabled.
Hi,
A shop sold me one of the India Airtel model Diamonds but told me it was a retail version so I am kind of in a pickle.
Can I enable the 3G with a radio upgrade? Or is it an actual hardware difference with these model phones.
Any help is greatly appreciatd. I am stuck with this thing in a country where I need the 3g to even use the phone... ack....
Sorry u cant use 3G cause the chip & processor is different, it does not have a 3G chip, hence the processor in 3G models named MSM7201A and in Indian model the chip name is MSM7206A (= MSM7201A minus 3G chip) Read Worldwide websites and compare with Indian Website diamond specs...
That makes it very clear. Thanks for your advice.
Very Good information !!!
So I'm going to buy a Diamond. I have 2 options. One is Tri-band and the other is Quad, but it will cost me $200 more.
So if I'm not mistaken, the hardware is all the same so all I would need to do is flash it to unlock the 850?
Thanks.
Actually they are not the same. The European Diamond does not have the hardware for US 3G. If you need 850, go for the quad band.
the indian diamond is not 3G at all...it's got a different processor MSM7206A for 2G (the default diamond processor is 7201) with the same 528 mhz speed
except for that, all other hardware is identical to the others

That is 100% untrue. The DIAM100 does not have a WCDMA 850 radio in it, and the DIAM110 does. Aside from that, there are also other hardware differences among the different iterations.
oh ok, so not all diamonds are the same?
That's no good. Is it written in the back of the phone exactly which model of the diamond it is?
So which is the model where I can unlock the 3G?
I've Googled around for the better part of the morning and not found an answer.... forgive the noob question. I'm a programmer, but I don't know much about mobile tech/programming.
I have an unlocked Treo 750 I use on T-Mobile. Software Treo750-2.25-ATT Firmware 1.54.27.00. I'd like to know if it's possible to use the T-Mobile US 3G network. I was told it wasn't possible due to T-Mo using 1700/2100 band, which the Treo can't access.
Would upgrading the radio version allow me to do this? If so, is that the only piece that would need to be updated? Which radio version? From what I've read, it and the ROM talk to one another but radio capabilities aren't determined/defined by the ROM. Is that correct?
Many thanks in advance,
Richard
Not sure but I think it will
Radios do not work like that. The antennas in the phone are calibrated to work on certain frequency ranges. It's the same reason that a normal FM car antenna would work poorly for shortwave or CB.
The radios in the phone are approved (at least for the US) to work on preset frequencies by the FCC as well, so they will not even have the capability to work on any other bands because if they were broad-spectrum radios, the phone would fall into another category of device as mandated by the FCC.
Thus, any phone will only work on the bands that it is designed to.
Hi,
I'm a new member to the forum, although I've been lurking for quite some time now. My interest peaked recently as I acquired my very first Android device, the HTC Dream.
I realize this may be an offshoot, but is it technically possible to flash a radio image that switches on / uses a different HSDPA frequency? I read that the G1 uses the RTR6285 chip, which purportedly supports the UMTS band 5 (850 MHz), even though it's not officially supported by the G1. Unfortunately, this is the only 3G band currently in use in the country I live in, which means I'm left with EDGE over the GSM frequency.
To put it simply, I'm looking to unlock the radio chip's frequency. Is this at all possible in software, or would a hardware mod be needed?
Thanks!
Hardware..
