WOW, here is the simplest of all jailbreaks ever released for the iPhone. @comex has created a website called jailbreakme.com which will allow you to jailbreak iPhone, iPhone 4 using a web browser including Safari.
All you jailbreak fans out there, here is the simplest and most easy jailbreak you will ever come across, a software jailbreak through a website which makes use of an exploit. Just visit http://jailbreakme.com through Safari or any other browser you use and just "slide to jailbreak" your device with one easy step.
This is by far the easiest jailbreak ever released for any Apple devices and supports iOS 4, iOS 4.0.1, iOS 3.1.3, iOS 3.1.2 and iPad 3.2.1. Definitely a great job by @comex and kudos to him for achieving this.
P.S. The website may appear down for many of you since it is under very heavy usage, you might want to try it again tomorrow if it appears down for you.
