I have a blackberry curve 8310. Every once in a while people send me text messages and I do not recieve them. All the messages in the phone disappear and no new ones show up. I can send them to people. At the same time, all of the call log has disappeared also. If I get a missed call and click to view it, it is gone. The phone acts this way for a while and then goes back to normal. Has this happend to anyone else and if so how do you fix it. Thank you.
