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.
