JailbreakMe 2.0 website: easiest way to set your iPhone 4 free
Now all you have to do to jailbreak your iPhone 4 is go visit www.jailbreakme.com from the device itself, then follow the instructions that appear on-screen.
Of course, you can’t do this if your running anything newer than iOS 4.0.1 — so all you devs are out of luck.
