Hi,
As you all may have noticed, has released their new 2.2.1 firmware.
OSX 10.5.6 users Please be aware that if you want to Jailbreak or Unlock you Apple device you have to download a crack so you can sucessfully put your device into DFU mode. However I advise you not to install the crack because once you have jailbroken/unlocked your device. Your Mac will start to slow extremely and crash your system regularly.
If you wish to Jailbreak/Unlock your device please do it with a XP/Vista Computer or pay someone do it for you!
Cheers
