Siemens SL56

The smallest phone in our roundup, the Siemens SL56 ($249.99 with a two-year contract; price varies by state) offers e-mail functions both built into the phone and through Cingular Wireless's Web services.

The Siemens SL56 is a lovely little cell phone with many possibilities and good battery life. The display and some software annoyances make it just slightly less interesting, but it's nothing major.

The SL56 is Siemens's most stylish mobile to date. It features the new innovative and sliding design from Siemens Cell Phones.
