 "Samsung Launches Ultra Edition 13.8 Z720")
Samsung has just extended it’s Ultra Edition range with the new Ultra Edition 13.8, also called the SGH-Z720. The 13.8 is a slider, just like the current top-of-the-line 12.9 D900. One of the main differences is the thickness, which has increased to 13.8mm. With the Ultra Edition series being a focus on ultra slim phones, this new addition may lead one to think that they’re not going in the right direction. After all, the slimmest phone in the series is exactly half of 13.8mm: its just 6.9mm (the X820).
The other (and more important) addition is HSDPA support. HSDPA–or High-Speed Downlink Packet Access–is also known as 3.5G, as it is the next in line after 3G/WCDMA/UMTS, offering faster wireless data transfer speeds. Apart from that, the phone supports tri-band GSM (900/1800/1900), GPRS, EDGE and 3G/UMTS as well.
The Z720 has a large 2.1-inch disply that’s 240x340 pixels, 20 pixels more in the vertical than QVGA (240x320), and supports 262K colors. The camera remains at 3 megapixels and a secondary VGA camera for video calling is also present. The main camera can also record video in MPEG4/H.263. Media playback is largely the same with MP3, AAC, AAC+, e-AAC+ and WMA support, along with a “digital power amp” built into the phone.
