Dev-Team has released updated version of Redsn0w 0.9.5 for MAC, named "Redsn0w 0.9.5b5-2", previous version was redsn0w 0.9.5b5-1. This version is also for jailbreaking iPhone 3G and iPod Touch 2G on iOS 4. New version brings a new feature of enabling battery percentage, in addition to multitasking and home screen wallpapers.
1. This version is for iPhone 3G, iPod Touch 2G users only, and it doesn’t hacktivate your phone. In simple words, your device wouldn't be unlocked after using it, so don't continue further if you want to use unlocked iDevice.
2. Our recommend is to wait for official public iOS 4 release, which is expected on 21st June.
3. It's for MAC users only.
The jailbreak procedure is almost similar to earlier releases of redsn0w, only difference is the added options of enabling multitasking, wallpaper and battery percentage which you will see while execution of redsn0w.
