After jailbreaking with comex's JailbreakMe, I've heard a lot of people say they get weird green pixels when they boot. It's happened to me too and I discovered it has NO effect on my device at all (iPod Touch 3G 32GB) -Thanks deadlyvirus for posting that. Here's an image of what happens on my device: Please Register or Log in to view images I don't know if it happens to all iDevices, but it has occurred on the following: iPod Touch 2G iPod Touch 2G MC iPod Touch 3G iPhone 3GS iPhone4 iPad If this happens to you, nothing went wrong. It is also normal for these funky pixels to change location upon booting. The spinning wheel is normal. If it stops spinning and your iDevice is frozen, restore your iDevice and then re-jailbreak.
