i used redsn0w to jailbreak my iphone4. current firmware i have on it is 4.3.4 and i wanted to update 5 too have all the cool new additions. i wanted to restore my phone first to get rid of the jailbreak, but after itunes is done backing it up (which takes a while) it comes up and says "The iphone could not be restored. This device isnt eligible for the requested build." i made sure i had the most recent itunes and i restarted my computer but neither worked. ive read people saying that there are settings i would have to change cuz the jailbreak doesnt allow you to restore, or id have to play around with the hosts, something like that that i didnt uderstand fully. if anyone could help me out that would be greatly appreciated. thank youuuuu
