Samsung again claims the title of world's thinnest cell phone with its new. Though we just reviewed T-Mobile's , a.k.a. the slimmest candy bar phone in the United States, Samsung pushes the envelope even further with the X820. Though it's just 0.27 inch (6.9mm) wide, the candy bar handset manages to offer a 2-megapixel camera, Bluetooth, and an MP3 player. Released for the European market this week (with China to follow in June), the phone doesn't have pricing yet. There's also no word on when we'll see it stateside.
