I have had my iPhone jailbroken using Cydia (Icy) for a day now, and found it useless. Anyways, I was using BossPrefs and it froze, so I held the home button and sleep button until it shut off. Now when I turn it back on, it stays at the Apple logo forever. I tried plugging it into iTunes, but iTunes won't read it. I don't care if I have to erase everything and whatnot, I don't care for the jailbreak apps and just want to use the iPhone again. I hope I gave enough details. Any help will be GREATLY appreciated! Thank you for your time!
