I have a jailbroken iphone 4s. When i jailbroke it, it was on firmware 5.0. I downloaded the update for 5.1 today and i forgot that i cant do that. So now it is stuck with the "plug into itunes" logo now. I've tried the hold power button and home button to get back to the lock screen but it hasnt worked. Also, I even tried restoring it completely, but itunes says the iphone isnt eligible so now im stuck.
