This is my 2nd Bold 9900 which does this. Sometimes 3 times a day and sometimes I'll get through a week without it happening but the mobile network shuts itself off. Then with other times the near field communication and or bluetooth will turn on. This is a work phone. On the weekend I did an update to the BB ID and it rebooted to a JVM 505 error so I had to reload the OS and I'm up to the latest of 7.1.0 Bundle 2840 and it still does it. I've talked to other people in other departments and some of them have the same problem. But then again not all 9900's do it. This is my 2nd 9900 and both had the problem.
Anyone else had this problem?
