Sony has announced three new mobile phones for UMTS 3G wireless networks, two of which already include music player functions.

The clamshell-format Z800 can play MP3 and AAC music files stored on a 1MB removable Memory Stick Duo. The memory card can also be used to store pictures taken with the built-in 1.3 megapixel camera, or calendar, contacts, and other data transferred from a PC over the phone’s Bluetooth short-range radio, infrared, or USB (Universal Serial Bus) connections. The Z800 works on UMTS and GPRS (General Packet Radio Service) networks in the 900-MHz, 1800-MHz, and 1900-MHz frequency bands, and will be available in the second quarter, the company says.

The soapbar-shaped K600i is a 3G phone aimed at the mass market. “Call it a T610 for 3G,” says Flint, referring to the company’s iconic GPRS phone. The K600i contains an FM radio, and can also play music tracks downloaded or transferred from a PC via a USB connection. Video conferencing is possible using the built-in 1.3 megapixel camera, and the phone comes with a game: Vijay Singh Pro Golf 2005 in 3D. The phone works on UMTS and GPRS networks in the 900-MHz, 1800-MHz, and 1900-MHz frequency bands, and will go on sale in the third quarter, Sony Ericsson says.

The third new device is a PC Card modem, the GC95. On UMTS networks, it delivers data rates of up to 384 kilobits per second, the company says. It can also operate on EDGE (Enhanced Data Rates for GSM Evolution) networks in four frequency bands (850, 900, 1800, and 1900 MHz), where it delivers data rates of up to 247 kbps. The card will go on sale in the third quarter, and is compatible with computers with a Type II, 32-bit Cardbus PC Card slot and running the Windows 2000, Windows XP, or Mac OS X operating systems.
