OK so I am new to the mac world jumping in head first. bought the new umbp when they were released after wwdc, and just switched from HTC tilt to the iphone. I bought the iphone from a good friend who upgraded and I had no issues till now. I can't get any apps to open up. When they are touched, it opens for about 1 sec, then goes back to the home page. Tried restarting and shutting down a couple of times. Still, no luck. Anyone ever have this too? Any suggestions? phone works, email works, camera works, ipod works, but no apps.
