The Bottom Line In spite of some minor irritants, the stylishly designed and feature-packed Sony Ericsson T637 doesn't disappoint. Sony Ericsson succeeds again with its third Walkman phone for the U.S. market, but the W810i brings only minor improvements over earlier models. If you want a high-quality camera phone from AT&T, you can't go wrong with the Sony Ericsson Cyber-shot C905a. Despite minor glitches and a high price, Sony Ericsson's P900 offers worthy features and extensive connectivity in a trimmer package. Carving out a spot between the T68i and the P800, this Sony Ericsson model offers the perfect blend of size and features.
