If you don’t have a 1.1.3 iPhone, upgrade to 1.1.3 using iTunes. If you do, skip to step 2 Download and unzip the new iJailbreak Quit iTunes and run iJailbreak with your iPhone plugged in (in normal, not recovery mode) Choose Jailbreak, then choose to either jailbreak it alone or also unlock for other sim cards. Wait 2 minutes – grab a coffee, use the bathroom etc. Done!
If there are any issues, re-restore to 1.1.3 using iTunes. This has happened 1 out of 10 times we’ve tried, the others were successful. It’s so easy, a thirteen year old can do it – actually – two thirteen year olds built the application! Edit: for all of the people who say they have a 1.x.x iPhone that is jailbroke/not jailbroke with xxx firmware and XXX Baseband…IT WORKS FOR EVERY IPHONE EVER MADE! Yours isn’t special unless you’ve done hardware mods – which is like 4 people. If you are on Tiger however, wait a few hours/days until the Tiger version of this application comes out.
