It’s 4.7 by 3 by 0.7 inches and weighs 6.7 ounces. The screen is H-P's 3.5 inch color model. Inside is a Texas Instruments OMAP 1510 processor. There’s 64 MB of ROM and 64 MB of RAM. Some models come with a VGA camera built-in. (My sample did not.) There’s also a mini-keyboard that snaps on the bottom of the 6315, but adding it makes the phone too large to fit into the provided leather belt holster.
The best part about this device is the 3-way wireless capability. I didn’t have much Bluetooth to try but I immediately connected the h6315 to my 802.11g wireless router and to the T-Mobile network. (T-Mobile will be the ones actually selling the device; expect to pay $499 for the phone in addition to the cost of activating a phone-data service plan with the mobile provider.)
Blinking lights above the screen indicate whether you're connected and it’s fun to turn them all on at the same time. When connected, the GPRS and WiFi indicators blink green; Bluetooth blinks blue.
