Samsung upgrades its Ultra slim phones to 3G
The Z370, the 3G variant of the X820, has UMTS support added, as well as microSD slot. It still has the 2 megapixel camera but also has a VGA one for video calling, and with its 8.4 mm it is only 1.5 mm thicker than the X820.
The Z620 3G clamshell is the upgraded version of the D830, as UMTS support is added and the 2-megapixel camera is now a swiveling one so it can be used for video calling too. The upgrade to 3G comes at a price of 1.9 mm added in thickness.
The third device is the Z720 and it is the 3G version of the D900 slider. The new handset still features the 3.2 megapixel shooter but also has a VGA camera for video calls added. There's HSDPA support included and with it's 13.8 mm thickness it adds only 0.8 mm to the D900.
There's no info on pricing and availability of the three new 3G handsets by Samsung, but it is expected that a launch may take place before the end of the year. Yet there's little chance that the initially released devices will be suitable for use in the US.
