What's the best way to unlock an iphone 4s?

What is the best program to unlock an iphone 4s? Legally you can still unlock them if they were manufactured before January 26th 2013. I have used a gpp sim before but the activation code only works on one phone.

The best way of unlocking the iPhone 4S will be getting is factory unlocked. It doesn't require software or Gevey SIM and everything works flawless. You can mail this person (arghyle@rocketmail.com) who can help you with the factory unlock.

To Unlock iPhone 4S using Remote Unlock Method is the best method. You can get the remote unlock service from http://www.prounlocking.com/apple-iphone-4s/rs16wp9/ for a reasonable price. There you have to give your Country and current network name along with your IMEI number to get the Remote Unlock service. Unlike other unlock methods, it is permanent unlock method, Once the iPhone 4s is unlocked it will always stay unlocked even after updating or restoring the iPhone 4s.
