The iPhone will be on pre-paid wireless plans when it makes its debut on the Leap Wireless network on June 22. The Leap plan is $55/month and includes unlimited voice and data calls and what the company labels as "unlimited" data, but which is actually 2.3GB per month. The catch: you need to pay $499.99 for the 16GB 4S (Apple charges $649 for an unlocked 16GB 4S). An 8GB iPhone 4 is also being made available for $399.99. You also only get access to Leap's 3G network.
