| 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 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. | 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 iPhone 4S isn't the king of cell phones, but it's part of the royal family nonetheless. Even without 4G and a giant screen, this phone's smart(ass) voice assistant, Siri, the benefits of iOS 5, and its spectacular camera make it a top choice for anyone ready to upgrade. |
