Pretty much the kitchen sink, no?
It's also set up to use a bunch of Telstra-related services, including Yellow Pages, 1234, Whereis and Foxtel.
Unlike the iPhone - even the new iPhone 3G S - the KM900f Arena handles video calling. (Is it just that video calling is a minority interest in the US, or does Apple have a problem with the whole idea?)
How much? $A829 on postpaid plans.
Oh, and one sign of iPhone envy can be seen in the way the publicity photo of the Arena has an Apple-style vertical reflection.
