Cell phones will continue their upward momentum as suppliers add more features. Motorola's Moto Razr V3 mobile phone, for example, incorporates a plethora of bells and whistles in one of the thinnest phones available. Mobile Action is introducing the Handset Manager to the U.S. This software solution integrates CDMA cellular phones with Windows-based PCs. This makes it easier to maintain and update phone numbers and address book information, synchronize a personal calendar, create and manage ring tones, manage images and exchange multimedia files. Over 15 million people worldwide are already using the GSM version of Handset Manager, says Fitzwilliam Yang, brand manager.
