Well damn ! I just posted about the workings of @geohot and his progress towards getting the next release of Blackra1n for the new iPhone4.

But it looks like the ever-diligent team over at The Dev Team (@iphone_dev) have just revealed a new unlock for the IOS4 and 3.1.3 basebands.

It’s pretty straight-forward:

  • Jailbreak
  • Launch Cydia
  • Add the source repo666.ultrasn0w.com
  • Install ultrasn0w 0.93
  • Restart


Disclaimer: I haven’t had the opportunity to test this myself yet (give me a few hours and I’ll try this tonight), but you can always proceed at your own caution and also check out The Dev Team site here.
