The A728, A732 and A910 target mobile professionals. Additionally, Motorola will partner with Yahoo on mobile-phone and iRadio product content.
The A728 appears to be a cost-optimized version of the companys earlier A760i and A768i (which in turn are tri-band versions of the dual-band A760 and A768, respectively).
Like those devices, the A728 is a tri-band 900/1800/1900 GSM (Global System for Mobile Communications) phone certified as conforming to the European Unions Radio and Telecommunications Terminal Equipment Directive.
But unlike the A760i and A768i, it lacks Bluetooth, and it has only a WAP2 browser. It has been available in China since the second quarter of 2005, Motorola said.
Basic features of the A728 include handwriting recognition, PIM and POP3 e-mail software, MMS client, WAP2 browser, SyncML support, voice dialing, hands-free connection, a built-in dictionary, and Yahoo instant-messaging software.
The A728 also offers an integrated MP3 player, MP3 ringtone support, MPEG video capture and playback, hands-free speakerphone, user-independent voice dialing requiring no prerecording, and a J2ME (Java 2 Micro Edition) runtime that supports games and other user downloads.
