    Hello I have an iPhone 3Gs running iOS 4.0.1 And I have the SHSH Blobs saved for iOS 4.0/4.0.1! I recently jailbroke it 2 weeks or so ago with I wanted to jailbreak it at the time but I also knew I needed to take it back to APPLE because it has a crack on the back that came up and I wasn't hard on it and apparently apple will take it back if you're within warranty.

    To get back on topic all I need to know is...How do I restore it back to iOS 4.0.1 so that i can take it back to an APPLE Store.

    Any help would be greatly appreciated! Thanks,JAMIE!!

    Personally, I'd just brainwipe it:

    First, plug it into iTunes and sync all the data, and make sure everything is backed up.

    Second, make sure your SHSH blobs are saved just in case, and do a DFU restore, setting up the phone as new. This ensures any trace of the JB is out of the phone's storage.

    Third, and I do this just to be sure, I do a complete reset from Settings. The DFU and restore should ensure that, barring someone going in with a low level tool on the Flash chips (bypassing the disk controller), there is no trace of the phone ever being JB-ed.

    In any case, just do a DFU restore and set up as new, and nobody will be the wiser.
