I tried to jailbreak my sister's iPod 3g 8gb with iH8snow's method, but I screwed up somehow, so I restored to 4.0. After restoring to 4.0, she lost the 3.1.2 blackra1n jb that has had since she got it. But now, unjailbroken, it clicks exactly 13 times after the locking noise, which adds up to 14. It seems to play the full locking sound once, then play 13 more shorter clicks after. It not that big of a deal, but i just wanted to know if anyone else was having this problem.
