HTC has to fix it, my friend's Fuze has less than 1 second of lag where I have at least 2 to 3 seconds lag under same app. My theory is that disabling the CDMA's FM part screwed up the GPS somehow.

As if the video performance isn't enough already, and I paid $400 for it? Geez HTC, come on...

Thats interesting... The fuze is GSM, less lag.

I see no to little lag and we have differnt chips and processors, memory, etc. Isint the GPS integrated on the main processor or is it somewhere else?

Tearing down my pro now to look at the guts. Post is in forum if you want to see what an XV6850 looks like.

From what I know, the GPS, the FM and the Bluetooth is in the same chip, not the processor.

Well then it would stand to reason that we on the XV6850 dont have the FM CHIP at all I was told... Then we must have a differnt GPS too then? Differnt rev of the chip.

Maybe thats why I see no lag? Possibility here? This is got me thiking....

One person said he saw lag on his 6850 but... Welll... I dont.

Thing is, nobody can confirm if the VZW's TP has a different gut than the rest of the CDMA world (except RAM size and keyboard).

I remember there was a post about those three things are in the same physical chip. Then again, if VZW decided to order something without FM, just like the rest of the CDMA world, HTC has to get a different chip, if not, a different design and that involves a lot of redesigning, this and that, which can be costly.

From a business stand point, minimum modification (GSM radio replaced by CDMA counter-parts) and left the rest core hardware in uniform, and leave the customization in the software part makes more sense than go with the hardware route.

My theory was, by disabling the FM radio, which is part of the GPS and BT chip, it somehow affected the performance. However it is possible that HTC know this issue, and quietly and secretly worked out with the manufacturer with that chip, with minimum change and quietly replaced them in the newer batch of phones.

Untill now... I tore my spare one down and have posted pics. Have not had time to compare them with the others but plan too soon. Not tonight though...

I dont have all the hi res up yet. Taken with 7 meg camera and at full res you can see the model numbers very clearly.

I will post the hi res one soon.... They are freakin huge though!

Well i never took my phone apart really, so I can't tell.

I guess it's just a mystery to be solved...

No, I am saying that others have tore apart the Sprint Pro... We need to just compare the pics and the chips now to find out.

No more sure than you so dont get me wrong at all. Thats why I tore it down. Sick and tired of specualting......
