Mobile carrier Hutchison in conjunction with US software company Seven Networks has introduced a competitor to the BlackBerry's mobile office solution, called Business Messaging. The service features push delivery of e-mail and calendar data, office address book integration, end-to-end encryption, remote data destruction, and integrated management tools for account management, the company said. A Web e-mail interface is optional, and the backend server sits on Windows. The Business Messaging service is available on Motorola's A1000 3G phone but support for other devices has been pledged. Looks like mobile messaging may become a standard if carriers plan to sell into the enterprise as workers become more unchained.
