Yesterday, Apple released iOS 5 beta 7 for iPhone, iPad and iPod touch to developers as well as the latest iTunes 10.5 beta 7. A little while after that, iH8sn0w released an update to sn0wbreeze. The latest sn0wbreeze 2.8b7 will jailbreak iOS 5 beta 7 tethered on Windows.
Sn0wbreeze 2.8b7 will jailbreak iOS 5 beta 7 tethered on the following devices: iPhone 3GS (new bootrom), iPhone 4, iPod touch 3G and 4G and the iPad 1. Only the iPhone 3GS (old bootrom) can be jailbroken untethered on iOS 5 beta 7 using sn0wbreeze 2.8b7.
Sn0wbreeze 2.8b7 will also allow you to remove UDID check as well as the beta expiry timer. Meaning that it not only will it allow you to install iOS 5 beta 7 without developer account, but it will also allow you to use the beta firmware even after its expiry date lapses.
