Is jailbreaking your iPhone illegal? - 1

I want to jailbreak my iPhone 4 but I don't want to get into any legal trouble. My friend did it and he can do some pretty cool stuff and it looks cool to but I just want know if ape can find out and press charges or something like that

I'm pretty sure it's not depending on how/where you do it. But your warranty automatically expires!

It's not illegal but it used to be a few years ago

It's totally safe, everyone does it. Although if something happens to it due to the jailbreak, apple won't be able to help you. Hope this answered your question.
