1 These devices can support an external USB keyboard with their USB hosting capability.
2 These devices support GPS through external Bluetooth GPS receivers. The iPhone does not support GPS at all.
3 The X7500 was released in March 2007, and contains WM5 and a secondary camera for video calls.
The X7501 was released in July 2007 and contains WM6, but no secondary camera.
Nearly all other features are the same.
4 The iPhone has a touch-sensitive screen, but it cannot be used with a stylus, or as a general pointer input device.
5 Contradictory reports exist on this feature; this is my best guess based on what I can tell.
6 The G920 has built-in GPS; the G910 does not.
All phones listed here have 900/1800/1900 MHz GSM, GPRS, Bluetooth, and WiFi.
Note: If a phone is not listed, it's probably because it didn't meet the inclusion criteria:
I currently own an XDA Flame. My preferences are in decreasing order in the table above.
