Samsung T578H phone
Samsung has announced an unusual new phone, the SGH-T578H. Key to its distinctiveness is support for TD-SCDMA, a protocol found exclusively in China, and at present only in 10 major cities; it does however support speeds up to 2.8Mbps, pushing the still-rare feature of 3G in the country. In 2008 the protocol will be upgraded to handle HSDPA, increasing speeds and potentially broadening compatibility. The phone is meanwhile capable of quad-band EDGE, GSM and GPRS, making it suitable for use inside and outside of China. TD-SCDMA is only available through a dual-band receiver. The T578H is merely a prototype, but will likely have a commercial equivalent in the near future.
