And with its basic Samsung silver shell, the X427 somewhat resembles the for T-Mobile service. While all three have a 65,000-color main display, however, the AT&T and Cingular models don't stack up in terms of features. For starters, neither has multimedia messaging or an external display, so you're forced to open the handset to see the caller's number--a rarity in flip phones these days. Other features, such as a 500-name phone book, 40 polyphonic ring tones, a calendar, a to-do list, a memo pad, a WAP 2.0 wireless Web browser, are basic, and the dual-band (GSM 850/1900) mobile is not a world phone. Though it's well priced at $119.99 or less with service, those wanting a full-featured cell phone should look elsewhere.
