6. HTC G2
Behold the power of "plus": HTC G2, which is T-Mobile's HSPA+ successor to the original HTC G1. T-Mobile couldn't promise a 4G network in time for the G2's release, but it did promise an HSPA+ data network, which offers 4G-like speeds of up to 21 Mbps. Physically, it's a smart-looking smartphone, too: a modified hinge with a slide-out QWERTY keyboard, Swype text entry software for its touch screen, an 800 Mhz Snapdragon processor, support for a 32-GB microSD card, and capability for Wi-Fi, GPS and Bluetooth. It also has a 3.7-inch display, a 5-megapixel camera with LED flash and autofocus, and 720p HD video capability.
The current version includes Android 2.2 and a number of additional Google-centric features, including Voice Actions for Google Search and integrated access to Google Voice.
