An improved version, the SL45i, was also the first phone to have a Java virtual machine. In addition to the MP3 player, SL45 offered other advanced features such as dictaphone with several hours of recording time, auto responder, voice dialing and voice commands, WAP browser, and context sensitive help in several languages. Other software include calendar/organizer, alarm clock, stopwatch, calculator, currency converter and games. While SL45 was one of the most advanced phones in its time, it was also one of the smallest.〔 〕 == Versions == The Siemens SL45 came in three versions: * Siemens SL45 - original edition, with a 32 MB memory card, sync station and stereo headphones in the package * Siemens SL42 - a cheaper version introduced later, with a 16 MB memory card and no sync station or headphones * Siemens SL45i - a version with a new firmware with Java support, and a slightly stronger battery These three phones are electronically identical, and the SL45i's firmware can be installed in the SL42 and SL45, thus enhancing them with a Java virtual machine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Siemens SL45」の詳細全文を読む スポンサード リンク
