    Can this be done? Would like to see a comparison of performance and battery between IOS4 and IOS5 on a 4S to see if these issues being reported are software related to ios5.

    It can't be done. Apple would have stopped signing iOS 4 by now (or will do shortly) and without a SHSH saved you couldn't downgrade that way
