My phone has stopped ringing (people call, it just rings and they get no voicemail) for the past two days. Only one call has made it through, and of course, that interrupted an important meeting. :/ Seems people aren't getting my text messages, either... yesterday I sent one and just spoke to them, they said they didn't receive it. I sent said person another one at that point (about an hour ago) and they did receive it. Anyway, I want to turn off my phone, then turn it back on, hoping that will help. Battery still charges; everything else seems to work fine. Can someone please help me? Once I can restart the phone, I plan on updating to 4.1.x Thanks!
