So yesterday, my daughter said she sent me a couple of pics but I never got them.. thought that was odd but didn't pay much attention. Used my phone normally yesterday, texting and surfing but didn't use Siri at all. Tried to use Siri this morning and it said on bottom of screen that Siri was unavailable and in my text screen, the little microphone was gone.. I then noticed the 3G symbol was missing at top of phone. I did a hard reset and it came back, then I got a flood of emails and all the picture text messages I didn't get yesterday. Does this ever happen to any of you?? its the first time for me since I got the phone in october. I hope it doesn't happen often because it remind me of my BB days of pulling battery and I never want to go back there again...
