iH8sn0w has now ported Geohot’s bootrom exploit in his flagship jailbreak tool Sn0wbreeze 2.8 beta 3 to jailbreak iOS beta 2 build 9A5248d on all iOS devices except iPad 2. As there is no untethered jailbreak for iOS 5 betas, we will have to boot it into a tethered mode using iBooty, except for iPhone 3GS which is on old bootrom.

Warnings
In order to prevent piracy this release does NOT Hacktivate or add afc2. You MUST be an iOS developer with a registered UDID to get through all the new activation screens. In case your device is already carrier unlocked using Ultrasn0w , just stay away, else you will lose your unlock.

How to Jailbreak iOS 5 beta 2 on Windows using Sn0wbreeze
Those who are unaware, Sn0wbreeze jailbreaks stock IPSW file, adds customizations and gives you a custom pre-jailbroken IPSW on Windows OS. You can then restore your iPhone, iPad or iPod touch with this custom IPSW in iTunes. Download sn0wbreeze v2.8 beta 3 and then follow our old guide on how to jailbreak iPhone, ipad, iPod touch using sn0wbreeze. However, if you are looking for Mac specific tool, use redsn0w instead.
