That is the phone I use for my international travel phone since it is unlocked. Works great. I only upgrade every two years so I will be unlocking my iPhone 5 for travel as soon as the iPhone 6 is released. AT&T will unlock it for you when your contract is up. I plan to gift the iPhone 4 to my housekeeper who is currently using a feature phone. I have all the original packaging so it will look like brand new. I'm sure it will serve her well for a few years to come.
