The T-Mobile G1 was the world's first Android-powered phone. Launched nearly two years ago, it created an entirely new class of mobile phones and apps. Its successor, the T-Mobile G2 with Google, will continue the revolution. The T-Mobile G2 will deliver tight integration with Google services and break new ground as the first smartphone designed to run at 4G speeds on our new HSPA+ network.
