The Nokia 3620 and Nokia 3660 are smartphones that succeeded the Nokia 3600/3650. Both run on Series 60 version 1.x on Symbian OS. They were introduced on October 9, 2003.〔http://company.nokia.com/en/news/press-releases/2003/10/09/nokia-changes-the-face-of-mobile-imaging-with-new-phones〕 Changes from the 3600/3650 include a conventional keypad (as opposed to the 3650's circular keypad ()), and a 16-bit display (as opposed to the 3650's 12-bit display). Both the 3620 and 3660 are basically the same phone, except that the Nokia 3620, being targeted at the US market, operates on GSM 850/1900, while the Nokia 3660, a European phone, operates on GSM 900/1800/1900. They use an ARM compatible main CPU (ARM4T architecture) running at 104 MHz. In the United States, the 3620 was carried by AT&T Wireless and Dobson Communications, while the 3660 was carried by T-Mobile USA. The replacement for the Nokia 3660 is the Nokia 3230. The 3620 does not have an official replacement, although it was replaced by the Nokia 6620 in AT&T/Cingular's lineup after the merger between AT&T Wireless and Cingular. ==References== be-x-old:Nokia 3620/3660 fr:Nokia 3660 hi:नोकिया ३६६० it:Nokia 3600/3650 pl:Nokia 3660 fi:Nokia 3660 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「Nokia 3620/3660」の詳細全文を読む スポンサード リンク
