Phone Review: Samsung Jack i637
This follow-up to the BlackJack II adds WiFi, a unique pressure-sensitive d-pad for fast scrolling, and steps up to a 3-megapixel camera. Other features are similar, including Windows Mobile 6.1 (upgradeable to 6.5,) GPS, QWERTY keyboard, memory card slot, and Bluetooth.
