I need a new cellphone.

This is an area of technology that I find kind of infuriating because of the lack of standardization and the desire to "productize" the ability of users to move different sorts of data. But anyway...

What I think I want is a phone that's really a phone (not a PDA) that has the guts to connect to the 3G data networks and which I can use thusly as a cellular modem for my lappy, which I'm rarely without in any kind of work-potential situation. Any pointers?
