Yamigo was a free communications service, based in Finland, that allowed instant messaging on mobile phones over wireless data services such as GPRS. The service was based on a protocol called Wireless Village, developed by the Open Mobile Alliance, which is a joint venture between Nokia, Sony Ericsson, Motorola and other mobile device manufacturers. Certain models of mobile phones that include a chat client could access the Yamigo network. These included certain models of phones from Nokia, Motorola, Sony Ericsson and Siemens. Once registered, Yamigo users could send messages to each other, and to users on Yahoo! Messenger, MSN Messenger, AOL Instant Messenger and ICQ. Yamigo supported importing contact lists from those services automatically. Users connected to Yamigo via WAP and the internet. On the service's sign up page, users selected how frequently their phone polled the Yamigo network. Because it is a client-server protocol, receiving messages depended on how often the phone was set to poll the network. The service was abandoned in late 2005, and the last upgrade was version .19 in April 2005. 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「Yamigo」の詳細全文を読む スポンサード リンク
