Is it illegal to hack the iPod Touch or iPhone?
Hacking the iPod Touch is not illegal. While Apple would like to make you think it is illegal, it is not, and it is impossible to get in any legal trouble for hacking it. You and Apple made an exchange. You gave Apple $400 and they gave you an iPod. It is officially yours and you can do whatever you want with it. It is illegal to post copyrighted code, such as the operating system of the iPod Touch and the iPhone, on the Internet. But you won’t be doing that if you choose to hack your device.
