My friend went to an Apple store in Swansea or whatever, and he wanted to get a warranty. The owner checked out his iPod and he said he detected unidentified firmware/software changes. My friend had his touch jailbroken for 2 weeks and fully restored it before he headed to Apple. I'm thinking this isn't a good thing. I hope it was HIS personal error or else. The warranty couldn't be completed, I hope were not screwed.
