George Hotz, the first to develop an unlock for the iPhone 3GS has released an updated unlock for the device.

The unlocking method which uses a similar, unpatched exploit found in the iPhone 3G has been streamlined. The new App called Purpelra1n, makes the unlocking process much easier and fixes previous issues with Purplesn0w.

Wifi fails? Battery fails? Unlock fails? You need purplesn0w, the geohot 3GS unlock solution. Now I know you here a lot about different colors of sn0w, but I’m here to tell you why purplesn0w is the best. First off, what is purplesn0w? It’s a soft unlock for your 3GS that I’d actually use day to day. It’s not a daemon that takes any resources, and it doesn’t add a task to your baseband. It’s very close to a true unlock.

However, there are some caveats such as the lack of support for “hacktivation” and some minor improvements are coming soon to the App. Your iPhone 3GS must be already Jailbroken using either QuickPwn, Redsn0w or Purplera1n.
