The Siemens SX1 is a tough sell, with its wacky keypad layout: All the numbers are arranged vertically, down both sides of the phone. On top of that, it’s hard to tell when these strangely placed buttons have been effectively pressed. But if you can get past the keypad, the SX1 is a solid smart phone.
The SX1 is carried by third-party retailers and will work on AT&T Wireless, Cingular Wireless, and T-mobile networks. For a phone, call quality is good, and so is the VGA camera. The built-in FM radio is a neat feature that uses your headset wire as an antenna.
As a smart phone, the device can sync to standard POP3/IMAP e-mail clients, SMS, and MMS. A WAP browser is preinstalled, but you can download Opera for free.
The SX1 has an external MMC slot that doesn’t require you to remove the battery to change it. Along with the card slot, there’s an adequate amount of internal memory (12MB) for documents and applications.
On our tests, the SX1 finished in the middle of the pack, turning in an overall SPMark04 score that put it in third place among the six phones tested.
The SX1 would be a leading Symbian contender if not for its keypad. We say stick with a more traditional smart phone like the Nokia 6620.
