The accounting system shows three versions:

  • iPhone PostPaid
  • iPhone PrePaid (Pay As You Go)
  • iPhone Hybrid (Pick Your Plan)

For clarification for international readers Cingular describes ‘Pay As You Go’ and ‘Pick Your Plan’ as follows:

Pay As You Go
Pay As You Go is wireless made easy. Simply pay in advance for what you need. No long-term contracts, credit checks or surprise bills - just all the benefits of wireless, with no complications.

Pick Your Plan
Get the best of wireless without long-term contracts or unexpected bills. With Pick Your Plan, you establish monthly automatic payments for service and use the balance on your account for voice minutes or other features. It’s that easy.

At this very moment it is unknown whether this is purely an error on AT&T’s system, but if true it would mean customers could simply pony up the money for the phone and use it with other networks.
