After a bit of delay, the greenpois0n iPhopne jailbreak is now finally available. This latest iPhone jailbreak tool is specifically designed to work with iOS 4.1 and is ready for download with various versions available for Windows-, Linux-, and Mac-based systems.
It’s a fairly easy to use jailbreak, but if you want a step-by-step instructional on how to go about it, there’s a helpful guide posted over at Redmonpie which can help you out in this department.
Just to remind you folks out there who rely on use an unlocked iPhone, while there are a variety of iOS 4.1 jailbreak tools already available (limera1n, redsn0w, and greenpois0n), there is still no known iPhone unlock tool that works with the new 05.14.02/2.10.04 baseband. As such is the case, be extra careful when updating to iOS 4.1 so as not to upgrade the baseband in order to preserve the unlock status of your iPhone.
