Great news for anyone who allows Sprint customizations to run on a Verizon XV6900: I got mine working on Verizon again without bricking it! My thanks to drellisdee and verizon tech support (negamann thanks for your suggestions but I waited for a safer method). Here's the basic outline of events (from the beginning of letting sprint customs run):
1. I loaded ImCokeMan's unlocker ver 2.31.
2. I loaded the Sprint ROM and MISTAKENLY let customizations run.
3. I re-ran the Sprint ROM and soft-reset before customizations ran again.
4. I called Verizon to re-authenticate my phone to get phone calls and sms working again. I regained phone calls but my data connection was broken (wrong user-name and password) and my phone also looked like it was "roaming". My GPS radio worked (so-so, took a long time for a lock).
5. I re-flashed a multitude of other custom ROMs (thanks to PPCKithen's BuildOS) to test various things but still had same results (good phone and so-so gps but no data and still looked like i was roaming).
6. drellisdee helped me with the rest. For the "roaming" problem, he directed me to the following post (

7. For the data connection problem I had a high ESN number (following the guidance on drellisdee's post at
http://forum.ppcgeeks.com/showthread...174#post202174) so I SIMPLY had to call Verizon and ask them to re-provision my phone for data connectivity. I explained a hard-reset wiped me out and now I can't reconnect. They had to escalate the call but within 15 minutes on the phone they had me connected again. I had to pull the battery out while they re-provisioned my network profile (i.e., re-authenticate). They also explained that when using *228, I should only select option 2 because that will both update and re-associate with the towers - she said it does more than activation option 1.
8. Now after testing a bunch of PPCKitchen ROM variations, I think I'm settling on OMJ's Custom Verizon ROM. IMO its the most complete and using it my GPS locks within a minute inside my house.
BIG sigh of relief after recovering from Sprint custom's running on my Verizon phone.
