iPhone Dev Team has launched Redsn0w 0.9.9 b6 for both Windows and Mac operating system . This also comes with fix for iPhone 3GS running iPad baseband 06.15.00 users by fixing network crashes during use of Location Services .
Update : Redsn0w 0.9.9 b7 is now avilable with even faster jailbreak speed .
Note : Baseband preservation is still not supported in 0.9.9b6 version for Windows . Redsnow still jailbreaks tethered boot only which means you have to connect to the computer to boot everytime you switch off your phone . You can re-jailbreak your device with this version but de-select “Install Cydia” option . iPhone 4S and iPad 2 are not supported as of now .
There is no ETA on the release of a untethered version for iOS 5 Jailbreak . In the meantime we will keep you updated about the latest releases and tutorials . Those who rely on carrier unlock should use Redsn0w 0.9.9b5 on Mac for baseband preservation .
