If you are talking about the Jaguar X-type Car, whether the Estate is a trim or not, then you must also be referencing the system where you can talk on the phone over the Bluetooth hook up to the radio in the car.
As such, most any phone that has 'BlueTooth connectivity' (from the Sidekick 3 on up) should interface with the radio, and work.
Bluetooth is a universal, non-Platform dependent thing that way.
If it works through BlueTooth, the phone can be anything.
