After getting off a 5-minute-or-so phone call with my friend, I can't seem to get my Phone application to work anymore. Launching it brings it to the keypad, which sits there momentarily but doesn't fully load, then crashes to the Home screen. I can call people via Contacts, but it never actually loads the phone app, and there's no interface (no keypad, no hang up, no speakerphone etc.) so I have to wait until they hang up for the call to disconnect. I can still send and receive calls and SMS, but the phone application is buggered. Syncing with iTunes didn't work, nor did a hard reset. I definitely do not want to restore and transfer everything again! I've read somewhere that some apps can cause these sorts of problems, like Kate, but I don't have that installed. What else can do it? I have Cydia, Installer, WinterBoard, BossPrefs... any ideas? Thanks!
