Calling and PDA Features:

The MDA's phone and PDA functions are designed to provide an integrated, seamless experience. A single main screen summarizes all the important information you need to make it through the day. Here you'll get message notification, upcoming appointments, dialing functions, tasks, and more all in one spot.

As a phone, the MDA features all the functionality folks expect from a cell phone, including a handsfree speakerphone, polyphonic ringtones, a vibrate mode, and picture and ringer ID. Microsoft Office Outlook Mobile combines email, calendar, contacts, tasks, and notes into a single application that seamlessly integrates with the MDA's phone functions. Meanwhile, headsets, car kits and other wireless peripherals can also be paired with the unit via Bluetooth (the Bluetooth 1.2 specification is supported).

Staying productive on the road is made possible by the Microsoft Office Mobile suite, which includes Word Mobile, Excel Mobile, and PowerPoint Mobile. Meanwhile, the File Explorer application makes it easy to browse the files on your MDA.

Like all T-Mobile phones, the MDA also supports voicemail, caller ID, conference calling, call forwarding, call waiting, call hold, built-in paging, and access to T-Mobile's 411 service.

Messaging and Internet:

Using T-Mobile's EDGE-powered internet service, you can surf the Web with the bundled Internet Explorer application, or use MSN messenger to stay in contact via instant messaging. Plus, the inclusion of Wi-Fi (802.11 b/g) in the MDA allows you to surf the Web or check your email at blazing speeds when you're connected to a Wi-Fi network. With the purchase of T-Mobile Hotspot data service, you can get online at thousands of locations coast-to-coast. Lastly, robust SMS and MMS functionality is built into the Windows Mobile interface, too.

One of the most important tools bundled with the MDA is Microsoft ActiveSync, which allows you to quickly synchronize your device's tasks, calendars, email, and contacts with your desktop. You also get Exchange ActiveSync, an application that lets you synchronize data with an Exchange server. Syncing can be done via USB, or wirelessly via Bluetooth or infrared.

Imaging and Entertainment:

Another great feature of the MDA is that it supports Windows Media playback right out of the box. With Windows Media Player, you can play streaming and downloaded video and audio content in a variety of formats, even purchased music from "Plays For Sure" supporting stores. You can also keep your tunes loaded on a memory card and listen to your music wherever you roam.

As mentioned, the MDA can take 1.3 megapixel (1280x1024) pictures, and while the camera is great for taking stills, it can also function as a camcorder, allowing you to capture video to the unit's memory. An integrated media application organizes your captured photos and videos. For gamers, the phone supports Java-based and Windows Mobile games.
