| The Bottom Line | The RIM BlackBerry Curve (aka BlackBerry 8320) for T-Mobile is the best BlackBerry we've seen to date as it offers Wi-Fi, best-of-breed design, and excellent performance. | Still offering an attractive design and excellent messaging capabilities, the addition of GPS makes the RIM BlackBerry Curve 8310 an even more attractive choice for road warriors. | The addition of Wi-Fi makes the RIM BlackBerry 8820 an even more powerful communication device for business users, taking it beyond just e-mail and phone calls. | The RIM BlackBerry Curve 8520 is a sleek entry-level smartphone that delivers some nice design enhancements and great performance. While available directly from T-Mobile, Wal-Mart offers the better value on the 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. |
