Curious if anyone has seen this? I tested it with two iPhones now. My company requires a 4 digit lock created on the iPhone when connecting to the Exchange Server. After connecting successfully, using the code works fine. BUT if you type the code in incorrectly at the lock screen ONCE, the phone reboots and keeps looping the boot up apple logo until you hook up to iTunes and restore from DFU mode. Let me know if anyone can verify this?
