Verizon - Flashing to Bell ROM

[djanu]

Hi All,

I am raising point once again which was once asked by drowe here but then never resolved....

Verizon - Flashing to Bell ROM
I have a Verizon xv6900 that has the 2.31 unlocker on it. I have flashed to other 6.1 ROMs, but am currently running the stock Verizon one. When I flashed back to stock, I let the customizations run (I like the version of Opera that comes with it) and my gps is non-functional. I've fought Valhalla, all the "fixes" that seem to work only for specific users and am wondering if upgrading the radio will fix the GPS. I went back to the stock ROM because the bluetooth works with my Redfly. I would trade that for working gps in a custom ROM.

If I upgrade to the Bell ROM with radio 3.42.50,

1. Will I get the use of the gps back?
2. Will I need a new A-key?
3. Will this lock me into using only custom ROMs?
4. Can I flash back to stock Verizon and will it downgrade the radio and poison the gps again?

Thanks for any help. I've read ImCoKeMaN's threads about downgrading radios and am just a little nervous about messing with the radio rather than just with the ROM.
