I've had my iphone for about a week now, and haven't had the opportunity to even jailbreak it yet, but suddenly from one day to the next (without even having plugged it into the computer that day or anything), the apps stopped opening. If I select an app, it shows its loading page for about 10s, and then just exits to the home page. I've tried restarting, resetting, resyncing, and nothing seems to solve the problem. Please help???
