Samsung has officially announced a new flip phone, but you can't have it. Unless you live in China, that is. The Leader 8 is exclusive to that country and packs specs that wouldn't expect to find in a phone that looks plucked straight out of 2006.

Flip phones are fine and still popular with guys as they fit in the pocket and don't require to be toted in a "man-bag".
Trouble is the battery is too small so I would never consider it.
