So i started with the tethered like everybody else (most people) and then went to untethered. Well, when i went to untethered my accelerometer stopped responding once, but a reboot fixed it. then i happened again, once again reboot fixed it. but after a while, it got to the point where no matter how many reboots, it didn't fix the issue. so then i restored to original 2.2.1, still didn't work, took it into bestbuy where i bought it, geek squad looked at it (for free luckily) and said to have apple replace it. so i called apple, they sent me a box which i have upstairs now, but.. during the free time i had between the box arriving and me sending it, i rejailbroke, (still of course no working accelerometer) but today the box came, so i restored to 2.2.1 again. and the accelerometer works... and i'm assuming if i send a fully working ipod into apple, they'd be upset. is there any way that the jailbreak could have cause the malfunction? and now that its restored it works again? but then why didn't it work after the first restore. ugh, something is wrong, but if it doesn't break again (haha, weird wish) apple wont fix it. ------------------double post merged------------------nevermind, i know so many people were concerned, i reboot 17 times, and it finally didn't work, so now i'll leave it on, and send it in! thanks for all the help?
