Cellular Unlocking

Re: Cellular Unlocking

just read an interesting article on unlocking IPhone 3GS. I hope it works,

"George Hortz posts about Purple Sn0w on his blog along with the instructions and advantages. Purple Sn0w is a light-weight and soft unlock as explained by George
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.
George also provides us with 6 simple steps to hackify the phone. Make sure to back-up before you proceed.

  1. Be sure to have legit activated 3GS.
  2. Disable 3G if you don’t have it.
  3. Add apt.geohot.com to Cydia.
  4. Install com.geohot.purplesn0w.
  5. Watch for success output in Cydia.
  6. Reboot, and enjoy your unlocked iPhone.

Please support George by visiting his blog and by following him on twitter. I am sure he has a lot more updates coming our way."
