So I was using PE 6.5 but eventually got sick of the 3G issues. Basically anytime I went into an area without good reception and lost 3G, it would not come back on when I got into good service. I would have to go into airplane mode to get it back, and even that took 2-3 tries. I said screw it and went back to 4.2. But I again am having the same problem...I went to go into airplane mode, put airplane mode on but then when I turned airplane mode off, the phone just randomly rebooted to the M logo. Is this just happening to me? Is there anything I can do?
