| The Bottom Line | 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. | 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. | The Nokia Lumia 900's unique design and high-end features make Windows Phone look fantastic, and the $99 price is extremely fair. Despite some flaws, this is my favorite Windows Phone yet. | The Samsung SGH-A187 has all the necessities of a text messaging phone. Although the occasional keyboard inconsistencies are frustrating, it's a solid choice for a good price. | 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. |
