| The Bottom Line | Although the Samsung BlackJack II doesn't bring any revolutionary upgrades, there are a number of welcome additions, including GPS and better performance, to make it a worthy successor and a good-value smartphone. | Although the Samsung BlackJack II doesn't bring any revolutionary upgrades, there are a number of welcome additions, including GPS and better performance, to make it a worthy successor and a good-value smartphone. | As the successor to the BlackJack series, the Samsung Jack brings a fresh look and some nice feature upgrades to make it one of AT&T's more solid and affordable messaging smartphones. However, we tend to favor the Nokia E71x's design. | The Samsung BlackJack heralds another 3G-enabled smart phone to Cingular's lineup. While it supports the carrier's video and music service, some design and performance issues trip up this otherwise sexy device. | Affordably priced, the Nokia E71x for AT&T is an incredible value for business users and consumers looking for a robust messaging smartphone. |
