Hi. You can get some good deals on unlocked iPhone models from ebay or amazon. Before buying an unlocked iPhone make sure from the seller, how was the iPhone unlocked. Certain unsafe unlocking methods would give iOS problem while working with other SIM cards. Temporary unlocking methods will also re lock the iPhone on your future iOS updates.
