Periodically my 9700 would not receive calls or SMS and MMS messages. I now have a new SIM card (as recommended by AT&T). I don’t seem to have that issue now but the phone seems to freeze at times (mostly text messages and sometimes while using the Internet). Today after freezing when texting I got the following message:
"uncaught exception Application net_rim_bb_messaging_app(86) is not responding; process terminated"

I was at home with Wi-Fi when this happened. What is going on? Do I need to return my phone (I have had it less than a year)? 😕
