So, this is a funny thing to notice so late, but a couple minutes ago, my phone was unable to send or recieve calls properly. Outgoing calls would have no calling tone and never connect and incoming calls would not pick up when I pressed the answer key. I rebooted the phone and this appeared to solve the problem, at least, temporarily. I'll post back in here if I have the same problem again. Anybody else get this at all? Since I, and I imagine many others, barely ever actually make calls with this thing, I wonder if it's a problem that has gone largely unnoticed.
