Looking for a data sheet on what is unlocked on this chip. I have the USCC Touch Pro2.
It is my understanding that Broadcom locked certain features of this chip and I am interested to know if anybody figured out how to "tweak" this chip by unlocking the locked features.

Somewhere in the many of threads I read, someone quoted Olipro stating that the the CDMA phones had the capability to do UMTS in the other bands, but lacked the appropriate antennas.
Now is there any budding RF engineers here who can compare and contrast the antennas is a Sprint/Verizon phone with a Tilt2?
Perhaps a small hardware solution could unlock the full potential of the CDMA phones?
Please share you thoughts, conspiracy theories.
Does any body know if it is possible and if so how to enable the HSPA: 850/1900 band on a Global (GSM/CDMA) Version of the TP2.
It already has the HSPA: 2100 enabled... so maybe someone RF inclined could shed some light on this question.
Thanks
I dont believe it has the hardware to do it. It is not a software tweak.
That is why so many people waited for the ATT version to come out. There is an Australian version that works on one of the bands but not both.
Sorry to say that I think you are wrong about the Hardware reason...
Apparently the Pro2 has the chip installed, but it's locked down some how. That info has been floating around from an inside source at Telus. they say it actually has 850/1900/2100 UTMS bands but just got "locked" by Telus.
Also sites like Engaget has long posted some HTC FCC info proving that; http://www.engadget.com/2009/05/20/htc-passes-cdma-gsm-hybrid-touch-pro2-through-the-fcc/
Also The TP2 uses Qualcomm's MSM7600. The specs for that processor allow two major sets of radio interfaces, only one of which supports CDMA 800 and 1900. That major set has two variants that support HSPA: 2100+800 or 2100+1900+850.
So the question is; is there anyone with the proper knowledge that can tell what is onboard the TELUS TP2 and if it has infact the variant that supports the North American frequencies, how do we enable it?
Thanks for posting with FACTS and not Thoughts as this is the only way we will get a valid answer to this question.
Hmm this is definitely an interesting idea. I'd love to have the front facing camera of the Global Version, but I still need 850/1900 UMTS
850/1900 WCDMA on Global version
Gentlemen:
While the chipset has the various frequency capabilities, it is the tuning of the antannae that determines which frequencies are recieveable , ie, turned on, in the various versions. The AT&T version has a different tuning of the antannae than the global versions.
While theoretically possible, the anatanne is part of the main board and must be physically removed and replaced. I have not been able to find a universal antannae that could be resoldered to the board, if one was brave enough to give it a try.
there is software changes to the chipset controller required as well.
I think it is pretty impractical and likely impossible to do outside of have a new board installed with the properly tuned antannae to make it work. I have researched this for some time now, in an attempt to be able to use the EU versions here in NA. I travel internationally a lot, to Asia and EU, and need the 2100 band, so that has been my motivation.
There may be someone else out there who has different information, but this is what I have learned in digging through the available data for the past 3-4 years of various HTC devices and their variants.
Hope this helps,
MWS
Who came up with the rumor that ATT's phone does not support 42Mb band?
According to phonearena it does,
http://www.phonearena.com/phones/Samsung-GALAXY-Note-II-AT-T_id7500
and Wikipedia also states the same bands for both, if not ATT's version looks better because of the LTE duo-band support
http://en.wikipedia.org/wiki/Samsung_Galaxy_Note_II
Am I reading this wrong?
is there any hardware difference at all? like if you unlock it, are they fully usable?
I think while at hardware level there maybe the same for both phones there are other things that potentially will lock it from using on different network even if it's unlocked. like ril and baseband. I am not a coder or engineer so I don't know all of the detail.
Thanks for the insight...

Hi all,
I've been trying to find more information on this but surprisingly I don't think anyone has actually asked.
What I would like to know is, does the Sprint version have the same hardware to support the same LTE bands? (And 3G)
I know that this device can be unlocked to be used on a GSM network via some of the methods here on XDA, although I'm not too sure if it's going to have full network support like the unlocked one.
Thanks!
As many of you know, Verizon disables the FM radio chip in the phones they offer that have them. I read elsewhere that they removed or changed the FM Hardware API in the Roms on their devices, blocking use of the chip. I believe it was in the HTC M8 forum that I read some people have been able to regain access to the chip by replacing the API with a functional one. I am unsure of all the details, but I wonder if it would be possible to take the API from, say, the Sprint variant and put it into the Verizon variant? I heard custom Roms are also able to restore the chip's functionality... Is there any way someone could confirm this?
