The Financial Times Germany reports that T-Mobile is giving Apple a revenue share of 10% of revenue derived from iPhone customers.

The FT reports further that Orange has a similar deal in France and O2 has signed with Apple to offer the iPhone in the UK.

These Apple iPhone deals for Europe are supposed to be announced officially at the IFA 2007 next week. This would be the first time that a handset maker is getting a piece of the revenue of the carrier. Nokia sure will want the same action for their next contracts with carriers.

10% is also quite high. Adding this to the money Apple already makes from each iPhone a new revenue record is in the future for Apple.
