UnTethered jailbreak iOS 5.1.1
Geohot, the creator of purplera1n, has just released his own iPhone 3GS software unlock and named it purplesn0w. Who is purplesn0w for? If you own a jailbroken iPhone 3GS running firmware 3.0 and you want to unlock it to use it with another carrier (T-Mobile only in the USA), then purplesn0w is for you. Are you experiencing wifi/battery/other unlocking problems after using ultrasn0w? Then I highly recommend you try purplesn0w. Geohot says that it’s the best unlock out there.
purplesn0w doesn’t run any deamon (resident app) on the iPhone, it just patches three files: CommCenter, lockdownd, and wildcard. You need an activated device in order to use purplesn0w, this is a minus.
Here is how to install purplesn0w:
Once you have followed the steps above, your iPhone 3GS should be unlocked.
Update: Geohot has also posted technical details of purplesn0w along with the source code of purplesn0w. He plans to release an updated version of purplesn0w with hactivation support.

Geohot released a beta software for iPhone 3GS jailbreak called PurpleRa1n. It is beta and has some issues, but it gets the job done if you’re patient.
Requirements: You must have
1) Windows xp sp2, Vista, Windows 7, MAC OS
2)
3)
The jailbreak is a bit incomplete. The kernel vm_mem patch is not present so Winterboard will not work as some other critical tweaks. (SBSettings does work!).
Use with caution and be patient. If you’re not in a hurry, wait for the release from DevTeam.
