This morning in New York, HTC, Google and T-Mobile put on a press event. The purpose: to introduce the HTC G1, first phone featuring Google’s new mobile operating system, Android.

Featuring tight integration with Google service to the point that the phone syncs only with Google’s calendar and contacts applications (no Outlook sync, but a GMail account is required), the HTC G1, and its Android operating system, is whatever you make it. Like the iPhone, the G1 has a built-in application store. Unlike the iPhone, “Android Market” is completely open; developers are free to publish whatever software they want to the system.
