Thanks for the reply. I had done a search on this forum and found a thread that suggested trying ##72786#, which I did, and I got an error message that my phone's activation couldn't be completed. And I could no longer make a call on my phone. Kinda freaked out, but cleared cache, dalvik, and did a factory reset (maybe overkill, but it's not a big deal to me), and it's back working. The PRL/Profile still can't be updated, but as long as everything else is working, I suppose I'll just let it go for now. If it becomes an issue, I'll just flash WS again. I never seemed to have a problem with that ROM.
Thanks again for the reply! (Oh, I did try the ##72787#, and nothing happened...not sure what's up with that.)
