My non-jailbroken iPod Touch 2g worked relatively flawlessly for almost a year. However, in the last two days, it has "crashed" twice. It went into some bizarre restart mode where the Apple logo displayed, and no combination of holding various buttons for 10+ seconds helped. It remained in this mode for at least five minutes. Since the warranty end-date is approaching, I'm a little concerned. Here's what I hope to learn: 1) How can I access a self-diagnostic testing mode on the iPod Touch 2G? 2) Is there any way that I can pay to extend the default one-year warranty? Many thanks. Update - Scratch #2... I just purchased a one-year extension on the AppleCare Protection Plan.
