No matter how many times I restore my ipod and jailbreak it again, my ipod continues to lockup at odd times. It may be when I'm adding sources, or when I'm browsing the internet. I'm beginning to think that no amount of restoring will fix it. I have even tried restoring using different computers. I have tried rebooting my computer and then restoring. I think it's a hardware issue..... However, I noticed something odd last night when it locked up. I was browzing the internet when it locked up. I noticed that on the top bar where the time usually is, there was a padlock in the locked position. I've never seen this before. How do I unlock it?
