iphone4 - do it at the shack!

Just got my iphone4. Radio Shack is offering up to $106  for your 3g 8g iphone. It makes the 2yr contract re-up more bearable and you can walk with a mini computer in your palm! The difference between 3G and 4 is spectacular! It's almost as much as the initial going from a blackberry to an iphone. The 16gb is amazingly fast. Internet browser speeds rival any desktop. The features in email of recognition of dates and addresses are nice too!
