so i've been having this problem for a while now. the phone locks up all the time, i have to hard reset it to come back on. usually when i do i will then recieve a bunch of texts that i hadn't had before(could be days old). My signal strength was always fine everywhere except in my office(ofc) but now i seem to have no signal anywhere unless im outside. calls go though but doesnt seem to ring on the other end, or someone calls me and it never comes through on my end. Same with text messages. I have tried restoring a couple times, im currently using the 3.1 beta 3 and it's still the same issue. Restarting the phone usually helps the problem but you cant tell when it starts to act up except for the freezing. Is anyone else having this problem? I'm thinking of taking it to the apple store for a replacement since its still under applecare.
