Snowbreeze v1.8 will be released soon to jailbreak iPhone 3GS (hopefully both old and new bootrom), iPhone 3G and iPod Touch 2G on iOS 4.1 beta. As you know sn0wbreeze is available only for Windows users.
It is to remind you that yesterday Apple released the expected iOS 4.1 beta (for developers) for iPhone and iPod devices mainly to address the reception issues along with improvements to prevent the unlock and jailbreak in future.
In this new iOS 4.1 signal strength bar for iphone has been improved, but I think this update won’t resolve the antenna issues completely as it seems a hardware problem. Other features are also coming in iOS 4.1 like game center, turning on/off spell check etc
iH8snow has just tweeted that the new Sn0wbreeze will be released soon but your iPhone/iPod should be pre-jailbroken on iOS 4.0.
Stay tuned for more information on release, download, and step by step guide.
