Greetings, can anyone please tell me if there is any way to get my T-mobile device to recognize other GSM frequencies? It is currently a dual-band pocket pc device and I would like to make it such that it recognizes the 850 Cyngular frequency in the US. In other words, how can I make my dual-band device a quad or tri-band device?

Hmm. i would say only by soldering. It's a hardware limitation of the device...
Stefan
The MDA/XDA II device is already tri-band.
or did I missunderstand you?
greets Alex

That's right. But the MDA/XDA I is only a dual band phone.....

Yeah, my device is only dual band. I thought that perhaps all these devices initially had the potential or ability to pick up any signal but that it was a software issue to actually start doing so. I am not too good with the techy lingo, but is there something called "soft phone"? I can't imagine companies manufacturing very similar phones overseas and in the US and the only difference being that one is dual band and the other tri band. It makes sense that these devices are all quad band and the company places limitations on them depending on where they are purchased
no the HF VHF and UHF and so forth need a frontend which cant just be programmed like that it have to do with filters and such as in before the signal ever get close to being digital and programmable
GSM BAND SWITCHING SOFTWARE
DOES ANY ONE KNOW WHERE CAN I GET A HOLD OF THIS? THANKS
hi Rudegar
can you shed a little more light on the filters and hardware change that would be required to change a frequency or activate another if the chip has it. ( sometimes it is capable but not activated )
I have been looking and i saw that the Verizon tp2 has this processor Qualcomm® MSM76oo™, 528MHz. and the Tilt 2 has Qualcomm MSM 7201a, 528 MHz. I was wondering if any of you guys know the difference between these?
7200 is CDMA, 7500 is GSM and 7600 is both.

though the att tilt 2 is gsm and the verizon touch pro 2 is cdma. (yes i know the verizon has a gsm radio too.)
Alexsha: It's actually the other way around. MSM72xx(a) is GSM, MSM7500 is CDMA, and the MSM7600 is the hybrid CDMA/GSM chipset.
The difference between the MSM7xxx and 7201 is the video encoding algoritm; the 7201 is sold in the United States with a less efficient video encoding algorithm because of a patent dispute with Broadcom over the 7200's encoding algorithm, though the MSM7200 is sold everywhere else.
This means that the MSM7600 can record VGA video, while the MSM7201a cannot. Otherwise, their processing power is pretty identical.
Thank you

Thank your help. I thought it was something like that, but couldn't find anything about it.
So I tried searching why the Tegra3 variant doesn't have LTE and the answers are more like "because the lte radio isn't compatible", I'm wondering why exactly is it not compatible?
Same goes for the SIII, it also has a LTE variant(Dual core) and a quad-core chip without LTE.
Its not like I'm suffering from the lack of LTE, its just curiosity.
Anyone ?

qualcomm LTE radio isn't and qualcomm wasn't helpful to Nvidia to integrate it with Tegra
so Nvidia had to make an LTE radio on its own hence the imminent Tegra 3+
Qualcomm wasn't helpful about it to Nvidia? Wow okay. So I assume the current LTE radios are by qualcomm only then.
Found a link explaining the snapdragon(in the lte variant of one x and s3). It includes everything basically, the processor, radio, etc. The Exynos Quad and Tegra3 don't include a LTE radio.
http://www.ibtimes.co.uk/articles/350403/20120609/samsung-galaxy-s3-exynos4-snapdragons4-variant.htm
From what I've read till now, people seem to be more happy with the dual-core S3 than the dual-core one x. Anyways Tegra3+ ought to fix that, its actually gonna be phone raping everything then lol! LTE, higher clocks, less nm manufacturing?
not most likely it will not be an nm shrink
Today, NVIDIA announced that their Icera 410 LTE modem has been approved for use in tablets and clamshell devices on AT&T’s network. While that does not mention smartphone use yet, this is a step towards LTE and Tegra 3 coming to the States in at least some form. As we have documented plenty of times, NVIDIA has been unable to pair its quad-core mobile processor with LTE because its biggest competitor (Qualcomm) is the only guy making LTE modems at this time and likely does not feel like sharing. With today’s approval, this should bring NVIDIA up to speed in no time (assuming they get the smartphone approval too).

I wonder if they'll do something like what Apple does and offer a subsidised trade-in for T3 HOX to T3+ HOX.
I don't think HTC can afford to, however much I would love to be able to
Am wondering if the 4g LTE generates a lot of heat when compared to the wifi version? Is there any difference between snapdragon processor and exynos in terms of battery life?

Hey guys,I bought a P2 recently.I had one question,is dual 4g supported in device? I mean I have two 4g Vodafone Sims but it shows 4g/3g/2g on one sim and 3g/2g on second.So this means it supports one 4g sim at a time right?
Thanks
Right and you can do nothing to change it . It is chipset dependent

U mean due to SD 625 ? I guess Redmi note 4x supports dual 4g at the same Time.

Not one snapdragon chipset can do dual 4G. Because mediatek patented it. And they don't share each other's technology because they are competitors.

Celoxocis is right.
To make it more complicated In Snapdragon family chipset 625 ( and others ) there are few modem chips
Think of it like a PC modem. You cannot have 2 connections on one modem. You need a seperate modem for each connection.
The chipset only has one 4g modem so only one 4g connection can be made at once.
Okay, got it! Thanks everyone
