XV6900 GPS Rev A upgrade help!

[ydoggy]

Hello... I'm pretty new to this and am struggling weeding out the Verizon issues and help out of all of these threads. Especially since there is a lot of weight to the Sprint version. I've read nearly all of the threads on flashing and radios and such, but am still confused. Sorry if my terminology is not correct. But I need some help.

I have a functional phone with problems:
-I get the Verizon splash screen
-GPS works
-A-key has been reset via Verizon tech support
-Constantly roaming phone coverage
-No data/internet (I have an unlimited data plan)
-Get an error code: 1020 error referencing Sprint (remember I have Verizon)when accessing internet apps

Following my best guess from the various threads and sources I did the following:
-Ultimately I unlocked successfully using IMCokeMan's unlocker 2.3.1 (by the way is this the Chief Engineer at HTC or something?)
-Installed (flashed?) the radio 3.37.15, except I accidentally let the Sprint Customization run.... I'm wondering if this is my problem
-Installed (flashed?)the OMJ's Verizon rom and seemed to be just fine
-Had some errors and read the threads regarding reseting the A-key. I called Verizon and they reset the A-key. I have the ability for incoming and outgoing calls, but it indicates that I am roaming.

First of all if anyone can make any recommendations on what I can do please help.

Some additional questions:
-I'm a bit nervous to retry the process since I'm not sure if I need to re-unlock with the 2.3.1 unlocker... I tried to rerun the 3.37.15 radio, but was received an error when flashing. Is there a way I can restart from scratch?
-Is my phone working correctly, but just need some adjustments in the phone settings from Verizon?

I previously had a XV6700 and used this site to flash to the WM 6 Rom and absolutely loved it. Decided to upgrade my phone to the XV6900 due to the GPS... I would love this phone too, if I could only get it to work as I had hoped.

Thanks in advance. In addition thanks for all of the developers that have done so much awesome work!
