The previous day, Apple pushed out the iOS 5 beta 2 to the developers with some bug fixes, improvements and some other changes. Now, the Sn0wbreeze 2.8 beta 3 is out to help the developers jailbreak the iOS 5 beta 2. As the earlier Sn0wbreeze version, b3 also provides an untethered jailbreak for the old bootrom iPhone 3GS. For all other devices, it is still a tethered jailbreak.
Also, the download file size as been reduced to just 15 MB now. The following are the changes in Sn0wbreeze 2.8 b3 as mentioned by its developer iH8sn0w :
Now jailbreaks iOS 5 (beta 2) * Intended for developers ONLY! * Does not Hacktivate or add afc2 in this release to prevent piracy. * iPhone 3GS old bootrom users have an untethered boot. * Now only 15MB :)
