Geohot released Limera1n for Mac OS X last night. Like Windows version, Limera1n for Mac OS X can jailbreak iOS 4.1 on iPhone 4, 3GS (Old+New Bootrom), iPod Touch 4G, 3G and iPad. As Limera1n do not support iOS 4.1 jailbreak on iPhone 3G and iPod Touch 2G, you can use this PwnageTool to jailbreak iOS 4.1 on iPhone 3G and Redsn0w (Win | Mac) to jailbreak iOS 4.1 on iPod Touch 2G.


NOTE: If you rely on an unlocked iPhone, do no update to iOS 4.1 directly as it'll also upgrade your baseband which is yet to be unlocked with upcoming version of Ultrasn0w. Either use TinyUmbrella (Only for iPhone 4) to upgrade to iOS 4.1 without upgrading your baseband or wait for PwnageTool to jailbreak iOS 4.1 directly on your device while preserving the baseband of your device.
