Though quite superficial, there's no denying that being thin is one of the most sought after physical quality. So we guess, the same goes for our today's technology especially for cellular phones.

It would be remembered that a couple of months ago, Samsung came up with a record-breaking 6.9 mm thin model, the Samsung X820. Now, there have been rumors going around that the company improved on the mentioned model by shedding off another millimeter.

While the exact model for this phone hasn't been announced yet, enthusiasts are referring to it as Samsung Ultra Edition 5.9. Some of the new phone's exciting features are listed below. Also, the phone is expected to be announced this coming February in a 3GSM show in Barcelona. If all plans go well, it should be available in the market by March.

Samsung X820 Ultra Edition 5.9 features:

• Only 5.9 mm thin
• Tri-band (GSM/GPRS/EDGE)
• 3.2 megapixel camera
• 80 MB internal memory
• Bluetooth (A2DP)
• Digital power amplifier
• Speakerphone
• MP3 and video player
• TV-out port

Edging out the competition with a mere 6.99mm statistic, the Samsung X820 is now the record holder for being the slimmest mobile phone in the world. But being so slim, how durable is it exactly?

Though its exterior may really appear to be fragile, it actually has an excellent construction. While its body carries no steel reinforcements, all parts are elaborated of plastics. Its weight of 66 grams attests to that.

Fitting nicely into your grasp, it really brings on a whole new meaning to holding the world in the palm of your hands. Its key features, other than its extreme slimness, include a high-quality horizontal display, 82MB of internal memory, EGDE and Bluetooth.

A shortcut button for the camera is installed on its right side, as well as a connector for both the earphones and the charger, which is protected by a rubber cap fastened to the phone body, and thus isn't easily lost. Situated on the left is the dual volume-control button, while the top area of the rear side is where the camera lens is integrated, thereby explaining that wedgy look.

Announced along an entire line of ultra-slim phones, (like the D830 which will be the slimmest clamshell ever, as well as the slider D900), the Samsung X820 comes in full black.
