Right. When I bought my phone I guess the OS that came with it was 2.0. I wanna go back to what it was when I first bought it. Would I have to download and install an earlier version? I say this because every since I upgraded to 2.2 I've been having problems. First no music app would work, then my phone would randomly shut off, now I can't watch any videos on the internet (non flash). It's just a pain in the ass.
Music apps work on 2.2 and the phone is not supposed to shut down. I assume you are not rooted? If that is the case, the first thing to do is a factory reset, as suggested to see if that straightens out some of your issues. If it doesn't, then contact Verizon. Your phone and the software are covered by a warranty. Good luck.
