Verizon is sending me a new phone!
For some reason the phone is locked in roaming mode, and I can send, but cannot receive calls. Anyway, the tech said this was a new problem to him.
I love Verizon's tech support personnel! Every person I have ever talked to has been very pleasant, and very helpful. Everyone kept apologizing for the problems I have been experiencing.
P.S. I installed the last official ROM from UTStarcomm's site (with Radio 1.10) before I contacted Verizon. So, there are no traces of the previous fiddling I have done.
