iphone keeps rebooting after ios 5 upgrade

My iPhone 3Gs 32gb keeps rebooting every 5 - 10 minutes after upgrading to the final version of ios5 that was released. When I try "restore" from itunes (when I am able to keep the phone on long enough that is) I get an error (1645).


Thank you in advance for any help, my iphone is pretty much useless until this is resolved!

iPhone 3GS, iOS 5

I just ereased all my contents and settings since nothing else seemed to work. It's fixed now but I have a feeling it might be an app that is making it crash so I'm not sure what i'm going to do about that considering I have no idea which one.

Hello, my brother had this same problem of the iPhone 3gs restarting cuz of the ios5. I tired enabling the 3G n dat but it only lasted for a few days them start rebooting itself again.... Try this method not sure how long it will last for but. Good so far.

General/reset.....Erase all data and settings.

On the iphone......Set up as a brand new iPhone.

Then log in with your apple i.d on your phone.

Once done, restore it from the pc and then sync ur backup with your apple I.d(if u hav 1) if u don't have back up saved it don't matter.

HOPE THIS HELPS YOU.

Because i know how frustrating it's been
