Apple has finally decided to start offering the iPhone 4 Unlocked to US customers. Ever since the new Smartphone was launched it was only available to users who was willing to get tied to a 2-year agreement with AT&T and since recently Verizon Wireless also got the chance to offer the Smartphone as well which was another contract-requirement catch to get the Smartphone. Now user have the option to choose between the 16GB model which goes for $649 or the 32GB model for $749. They will be available in Black and White but there is one catch, the iPhone 4 supports micro-SIM cards so unless your carrier has those cards then you might have to switch carrier. They are available from all Apple Stores in the United States.
