The iPhone Dev Team (Comex) has just unleashed a new jailbreak tool for all iOS devices and it’s done through Mobile Safari! Head to www.jailbreakme.com from Safari on your iDevice and get going! This is the “JailBreakMe 2.0 star” jailbreak for this into all the codewords.
The servers are definitely stumped right now so try www.jailbreakme.modmyi.com — that worked for us.
We can verify that this jailbreak is meant to run on all iOS devices including iPad and iPhone 4 with iOS 4.0 and 4.01. It will not work on iOS devices running iOS 4.1 beta.
Update: We’ve got video on iPhone 4 and iPhone 3G!
