In this tutorial I will show you how to unlock your (CDMA/WCDMA) Sprint or Verizon iPhone 4S on 5.1.1 with baseband 2.0.12 for T-mobile, AT&T, or any other GSM carrier.  I have personally unlocked 5 iPhones with this method and you can watch the video for a demonstration.

For this unlock you have to a Gevey Ultra S.  Apple n Berry sells them but we recommend to buy them from ebay for half the price.  We buy from this seller - http://www.ebay.com/itm/221051012657?_trksid=p5197.c0.m619#ht_3076wt_1377

Step 5.  Reboot again.

Step 6.  When your phone turns back on, wait for a pop up message to appear and give you your license number… Write it down!  Hit the Accept button.
