Redsn0w 0.9.7 for Windows to Untether iOS 4.2.1 Jailbreak with iOS 4.1 Firmware.

The iPhone Dev Team has confirmed that a Windows version of Redsn0w 0.9.7 is on its way. This version will jailbreak iOS 4.2.1 with iOS 4.1 IPSW instead of iOS 4.2b3 firmware and SHSH blobs.

"Since Apple still serves the 4.1 IPSW (not blobs!), we’ll do a Windows redsn0w release for untethered 4.2.1 via Monte-4.1"

Unfortunately the Windows version of Redsn0w 0.9.7 will not be as fast as its Mac OS X counterpart. This is mainly due to the fact that the Windows version of Redsn0w 0.9.7 will be using filesystem instead of RAM. This will significantly slow down the entire process or as the dev team puts it:

"Please don’t complain too loudly about how slow it takes The Win version uses filesystem instead of RAM: slow!"

Stay tuned for more!
