I jailbroke my iphone 3g running 2.2.1 with quickpwn and it froze. Now when i turn it on all i get is the apple logo and a loading pinwheel. When it is plugged into an outlet it chimes as if it was just plugged in every 10 seconds or so but then seems to restart after about 5 min. Please help! i really dont want to have to restore its factory settings
