Going to be on a business trip and i realized there is gonna be a Apple store around the block from my hotel. My 3Gs 1 year warranty expires on July 8th and ive been meaning to get a replacement due to i find it acts slow and i tried restoring it and everything but just doesnt seem to fix it. The store is in Toronto on Yonge St. Eaton Center. So what i was gonna do is book a appointment at the genuis bar one of the nights and go in and try and get a brand new replacement before my warranty is up. Is it as easy as walking in and getting a replacement or what? My iphone is currently jailbroken so id restore it back to original before doing anything. Also is restoring it now that its jailbroken same procedure as before? Im running 4.0 on it. Thanks!
