T-Mobile International and Research In Motion have plans to support a wider choice of devices with push-based BlackBerry email services through the introduction of BlackBerry Connect and BlackBerry Built-In, starting with the T-Mobile MDA II and MDA III.
Support for BlackBerry services will be initially introduced with T-Mobile's MDA II, a Windows Mobile Pocket PC Phone Edition; and the rollout with other devices is expected to continue in early 2005 with T-Mobile's MDA III (Windows Mobile Pocket PC Phone Edition), Sony Ericsson P910i (Symbian UIQ), Siemens SK65 and Nokia 6820.
RIM's BlackBerry Connect licensing program enables mobile device manufacturers to equip their handsets with the integrated ability to connect to BlackBerry Enterprise Server and BlackBerry Internet Service.
With the BlackBerry Built-In licensing program, mobile device manufacturers can incorporate various BlackBerry applications into their own devices including BlackBerry Email, BlackBerry Calendar and BlackBerry Browser applications. The first device to support BlackBerry Built-In is the Siemens SK65.
BlackBerry platforms for both corporate and personal email use are supported. For corporate customers, BlackBerry Enterprise Server software tightly integrates with Microsoft Exchange or IBM Lotus Domino to enable secure, push-based, wireless access to email and calendar. For individuals and smaller businesses, BlackBerry Internet Service allows users to access multiple personal and/or corporate email accounts (including many popular ISP email accounts as well as Microsoft Exchange and IBM Lotus Domino accounts) from a single device.
