I had fixed this same problem today.
Things to check:...
1.) Do *228 and press 1 to re-program the phone. then make a test call and see if you get anything to work. Try logging onto the Internets...
2.) That dosent work? Do a hardboot and wipe everything out. I noticed I needed to have the full verizon install and didnt skip it. "although I am sure you can skip it and have it still work. But..., to test it... just let it fully install" after the
hardboot "2 soft keys and reset" do the *228 option 1. and then option 2.
3.) Didnt fix it? find and download the verizon
stock WM5 ROM and install that .. then try to do all of the above. if everything works there... then Install the WM6 ROM. re-test it.

4.) Another option:
Call Verizons Tech support and ask them to re-install your data/EVDO mine was corrupt.. It took them 2 hours to figure it out...
If any of these suggestions do not work, then I would
call Verizon tech support or log into irc "

I hope this helps and please post back in here so Others that search this can get some help... I pretty much had to figure it out with a few other people. some VZG guy helped me out a TON on this and I give all this credit to him for sure!
