Siemens has unveiled its M50 Java-enabled mobile phone at the CeBIT show in Hannover. Integrated Java will also enable users to download various games and applications onto their phone. The dual-band GSM phone comes equipped with class eight GPRS for high-speed, always-on connections, and is expected to ship in June for about £130. Its support of the MMS (multimedia message standard) means that users will be able to send and receive images and ring tones, and the phone will be able to display pre-loaded images of the caller on its 101x64-pixel black and white display. The M50 is expected to be available in June, and a colour screen model is likely to follow. Thanks to so-called Magic Buttons, said Siemens, users can access applications such as games or the Internet with a single click. According to the company, the 650 mAh lithium-ion battery will provide up to 260 hours in standby mode and up to six hours of talk time.
