The ZTE U990 (not to be confused with the LG U990), the world’s first high-end HSDPA-TD-SCDMA phone, has been unveiled by ZTE Corp. in China. Using HSDPA, the device is capable of transferring data at the rate of 2.8Mbps — not too shabby, and apparently the fastest capable on a TD-SCDMA network (a network which is quickly being built out in China). The upload speeds aren’t too bad, either, at 384kbps, so using data and browsing the ‘net on this device could be a pleasure if the processor doesn’t cause too much lag. The handset is sporting Windows Mobile 6.0, which most either love or hate, on a touch-screen interface. It also has A-GPS for globe trotters or anyone who’s easily lost, but it’s data support outside of its native network includes only EDGE… probably one of its only downsides, but we suppose it works in a pinch. Are any of our Chinese readers considering snagging one of these?
