i have a 3gs that i jailbroke with jailbreakme.com a few weeks ago. today it froze and when i tried to restart it, it shows the apple logo with the spinning wheel and it just keeps spinning. What can i do if i dont want to restore it because it will upgrade my phone to 4.0.2 and i still want the jailbreak? I dont have any blobs saved or any of that because i didnt know how to do it. someone please help.
