Sn0wbreeze 2.0 was released earlier today to jailbreak iOS 4.1 on iPhone 3G, 3GS, iPod Touch 2G and 3G. Since it created some issues like iTunes error 37, iH8sn0w released Sn0wbreeze 2.0.1 to resolve the errors. But the 2.0.1 version of Sn0wbreeze too is creating error 17/40. So iH8sn0w has found the fix for it and has released the Sn0wbreeze 2.0.2 to solve it.
Change log includes:
*Fix for Error 17
*Fix for Error 40
*Fix for Hackivation issues
