Few moment ago we broke the news about the release of redsn0w 0.9.6b4 to jailbreak iOS 4.2.1 on iPhone 4, 3GS, 3G, iPod touch 4G, 3G and iPad with working Cydia and MobileSubstrate, as we told you earlier that redsn0w 0.9.6b4  is based on GeoHot’s limera1n bootrom exploit.

The bad new is that right now, the redsn0w 0.9.6b4 is a tethered or semi-tethered jailbreak for some devices (i.e. you will lose your jailbreak every time you reboot your iDevice, so you have to follow the following steps every reboot to have a jailbroken device )

Untethered Devices:
  • iPhone 3GS (old bootrom)
  • iPhone 3
  • iPod touch 2G (Non-MC Model)

Tethered Devices:
  • iPhone 3GS (new bootrom)
  • iPhone 4
  • iPad
  • iPod touch 2G (MC Model)
  • iPod touch 3G
  • iPod touch 4G
