GeoHot, the developer who brought us the purplera1n jailbreak, has released his iPhone 3GS unlock, purplesn0w. Below is what he has to say about purplesn0w and instructions on how to install it. You can view the original post HERE. This unlock is said to fix Wi-Fi, Battery and Unlock failing issues experienced with the ultrasn0w unlock.

Note: This unlock is different than the unlock released by the Dev-Team (ultrasn0w).

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. All it does is patch three files, CommCenter, lockdownd, and your wildcard activation plist (which you need, activate w at&t sim first, no hacktivation support yet). That’s it, no other files are installed. Props to Oranav for the at+xlog exploit!

A full explanation is coming soon, but I think you clever reversers out there will see what it does, and see why it’s so pristine The payload is radically different from other varieties of sn0w. beta as usual, back up first.

Instructions:
- Be sure to have legit activated 3GS
- Disable 3G if you don’t have it (like T-Mobile).
- Add apt.geohot.com to Cydia
- Install com.geohot.purplesn0w
- Watch for success output in Cydia
- Reboot, and enjoy your unlocked iPhone

Last night we released updated versions of our redsn0w jailbreak and ultrasn0w carrier unlock. These versions are now compatible with the iPhone 3GS running at 3.0. Welcome aboard, 3GS owners! (The tools of course remain compatible with all of the other platforms too.) Also last night, saurik released 3GS-compatible versions of MobileSubstrate and WinterBoard, components that enable many different add-ons and themes.

We realize we upset some folks (e.g. existing 3GS owners) with our earlier announcement that we wanted to hold onto the 3GS iBoot-family hole until 3.1 was out. Our aim there was to get as many people as possible onboard (within reason of course) before revealing the hole, since Apple will fix it immediately. But all of that became moot when the purplera1n release was made, since it uses the same hole.

For those of you who already own 3GS phones, the outlook is bright. As long as you have your personalized (signed) dfu/img3 files, you’ll always be able to jailbreak (even if you slip up and install stock Apple firmware in the future). For those of you without 3GS phones, it’s a race against the clock to use this particular hole. There’s nothing we can do about that, but we will always be looking for new holes.

There is an update to ultrasn0w, iPhone software unlock, to version 0.8. This version of ultrasn0w is said to work on the iPhone 3GS according to MuscleNerd, a Dev-Team member.

Things to Note:
    • “Ultrasn0W 0.8 (incl. 3GS support) (see Cydia).”
    • “ultrasn0w is now 3GS friendly! First cross-platform carrier unlock, thanks partly to Apple Repo details at http://is.gd/1pRGL.”
    • “The main 3GS ultrasn0w glitch on hacktivated devices is: need to do Settings->General->Reset->Reset Network settings once.”
    • “If ultrasn0w already works for you, 0.8 won’t add anything new. This 0.8 is mostly for 3GS users or 3G outliers.”!–more–>

That means that the iPhone 3GS is now unlockable. All you need to do is go into Cydia and install ultrasn0w 0.8. If you are on a hacktivated device make sure you follow the instructions above.
