Having read about 10 of these threads on several sites, I'm still left with a few nagging questions. If someone more knowledgeable can just give me a few quick yes/nos/maybes to the questions below, I'd be surer of the course ahead. It may look like a long list, but I promise, they should all be answerable with very short replies.

My phone started out as a much older pre-MR1 version that I don't recall the version number of. I flashed both MR1 and MR2 and a newer radio before re-flashing to the custom ROM (6.5) it currently has and the latest radio (3.42.50). This was all done before I had tried to use the GPS and before I had any idea of what it would do to those functions.

Question #1 - Is there a chance the radio physically in my phone is not GPS compatible? Or is GPS function of the xv6800 determined entirely by the software (and Verizon's whim)?

Question #2 - What you are saying is that I will have to downgrade this phone, relock it and bring it back to an older ROM (PRI 1.35 or there abouts) so that I will be able to get the GPS working?

Question #3 - Once I have it downgraded, do I have to do anything to it to remove that Verizon lock? Other than running the Valhalla.cab, or the other steps well documented on this and other sites, that is?

Question #4 - Referencing the webpage - http://wiki.xda-developers.com/index...VerizonAGPSFix - suggests I don't have to downgrade first and seems to suggest a different solution than using the Valhalla .cab. Which route is more effective (easier/quicker)?

Question #5 - Once the lock is removed, it sounds like can then load the latest radio and ROM back on and GPS will still function. Is this correct? (aGPS, or standalone, I don't much care - since I've never gotten anything to work with it except using an external bluetooth GPS receiver.)

Question #6 - My 'control' phone is as it came from Verizon, but it's ROM (v3.57.605.2) and radio (3.37.78 ) were already pretty current. Will I have to downgrade that one to remove the Verizon lock or can I just apply the stock fix outlined here - http://wiki.xda-developers.com/index...VerizonAGPSFix ?

I'm doing my research, and am ETERNALLY grateful for all the great work you selfless folks have done and posted here, but if I can get just a little bit of guidance here, I think I'd have this thing licked.

PS: Mods, this might belong in the 'Official Internal GPS..." thread. Sorry - I've been reading through so many threads, I probably didn't realize where I was!
