Yes I did! How do you completely wipe out the phone kind a like window format like a fresh copy, for some reason restore on itune really not re-format. my iphone kind a funky just not running smoothly and i would like to wipe-out completely like the original factory setting a clean slate,"Baseband" my wifi still greyed and showing N/A. I got the phone from 2.0 and now to 2.1 and still no wifi kind a sucks, Any cure for it !
BTW my other phones I think the problem with the bootloader the phone can't boot, even a new and a fully charge battery, still nothing on the screen.
