How to unlock sprint iPhone 5, 6.1.4 for overseas use?
I have a sprint iPhone 5, 6.1.4 that i'm currently using with sprint, how can I unlock it so it can read a SIM card from a different carrier overseas? I tried unlocking it through sprint but they told me I had to have had the iPhone for at least 90 days (currently 40 days or so), I'm only using it overseas with a different carrier not here in the US, can you help me?
