Orange UK HTC hero. unrooted Firmware version 2.1-update1 build number: 3.32405.2 CL191507 Problem: phone starts in airplane mode with sim card. It will not turn off airplane mode and crashes within a couple of minutes. Without a sim card the phone does not crash and works fine for email etc. This sim card works fine in my wife's HTC desire. Her card gives the same problems in my phone. I have done a hard reset and get the same problems (could only get the reset to work at all without a sim card otherwise I got the same crashes). Any ideas?
