Earlier today, Apple seeded Beta 3 version of iOS 5 for iPhone, iPad, iPod touch and Apple TV to developers. The new beta 3 version includes: custom tones for tweets, Assistive Touch with Gesture Control, speed improvement, along with usual bug fixes.
While MuscleNerd of the iPhone Dev-Team has already confirmed that the existing version of Redsn0w 0.9.8 (Windows/Mac) for iOS 5 can jailbreak the Beta 3, another iPhone hacker ih8sn0w has just pushed an update to Sn0wbreeze for Windows which can not only jailbreak iOS 5 Beta 3, but can also preserve the baseband for iPhone 4 and 3GS users who rely on Ultrasn0w or Gevey SIM unlock.
Remember, this is a tethered jailbreak for all devices except for old bootrom iPhone 3GS. iPad 2 isn’t supported. Also, this is intended to be used by developers only. Please proceed with caution.
Full release notes are attached as follows:
sn0wbreeze v2.8b4 — For iOS 5.0 b3(9A5259f)
* Intended only for developers (as usual).
* Hacktivation is disabled (again).
* MAKE SURE YOU UPDATE TO iTunes 10.5 BETA 3!

Those wondering, the jailbreakme exploit
cannot be integrated into applications
such as PwnageTool/redsn0w/sn0wbreeze.
redsn0w seems to be having sandbox errors
due to it using the old b1 kernel.
I and many others have not seen any issues
with sn0wbreeze related to App Store apps.
If you prefer to use redsn0w, I am sure
@MuscleNerd is working on a fix.
