Hi, I've had my iPod but i only use it for music, and accessing the internet and games, but in the past few days, when i try to listen to music after a few songs it just stops playing and returns to the home screen, and shows that there is no music playing. This has also happened when trying to run more graphically intensive apps, any help? Also my best friend who is NOT tech savvy at all has been having a problem with his and wanted me to have a look at it for him, as it isn't mine i didn't want to do anything with it until i had a better idea of the problem and the solution. His device will turn on but then only shows the "please coonnect to iTunes" screen. The problem is he had a password protecting it, so when i try to connect it, it says please enter password to access iPod. Any help there? Much appreciated!
