How to jailbreak iOS 5 on MAC with Redsn0w

24 hours after the releases of iOS 5, iPhone Dev Team released Redsn0w 0.9.8b 1 to jailbreak it on MAC, now users can install Cydia into their iOS 5 device.

Warning: this is not a perfect jailbreak, every time you restart your iPhone, you need to run Redsn0w. In addition, Redsn0w will not unlock your device.

This tutorial does NOT apply to iPad 2. We have only tried it on iPhone 4, so please be careful when jailbreak your handset. Also the Windows version of the Redsn0w is not available yet, which means you can use it on Mac only.

Please backup all your personal data before go ahead. For the tutorial please visit here: How to jailbreak iOS 4.3.1 for iphone via Redsn0w 0.9.6
