So I was happily searching Cydia on my unlocked Iphone 4 I just bought (im almost possitive it was on 4.0.1) and I downloaded an app "appsync" and my phone rebooted and got stuck on the apple logo, it would reboot and reboot not getting any farther then the apple logo... So I decided to restore it using the 4.0.1 ipsw, but it simply will not get any farther than "verifying" before I get an error. Im pretty new to all this and I'm not quite sure what SSH files are and doubt I have them. Is there anything I can do to save my unlocked Iphone? Please help.
