ok, i have an ipod touch 2g and it is jailbroken. i have a little problem with it though. there is lint UNDER the screen. so i want to restore it so i can exchange it for another at an apple store (i know u can do that, ive read on some forums with people with lint under their screen and all they had to do was bring it to an apple store an exchange it for another one). the only thing though, is that how would i FULLY unjailbreak it. like idk if its just as simple as just restoring it on itunes, or if i have to do something else. if anyone knows how, please post the exact steps in unjailbreaking it so that there is no evidence of it ever being jailbroken. thanks for any help EDIT:also, it has a few scratches on it(im not returning it so i can get one without scratches, i just dont want the lint)would they accept it?
