| The Bottom Line | Despite a few misses, the Palm Centro for AT&T is a solid, easy-to-use, and affordable smartphone for first-time buyers. | For those who waited, the RIM BlackBerry Bold won't disappoint. The Bold impresses with its brilliant display, enhanced productivity tools, and excellent multimedia performance to deliver a more powerful and well-rounded smartphone to mobile professionals. | The Palm Centro isn't the innovative product we were looking for from the company, but with its slimmer size, ease of use, and affordable price tag, the Centro is a good option for those looking for their first 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. | Though it has a few design quirks, the AT&T Quickfire's impressive feature set and intuitive controls make it one of the better messaging phones out there. |
