The T-Mobile Dash operates on GSM 850/900/1800/1900 networks and can handle high-speed data connectivity via T-Mobile's EDGE network (which stands for "Enhanced Data Rates for Global Evolution"). This high-speed, mobile data and Internet access technology is fast enough to support a wide range of advanced data services (with average data speeds between 75-135Kbps), including video and music clips, full picture and video messaging, high-speed color Internet access, and e-mail on the go.
Download cool new games, HiFi Ringers (real songs by today's hottest artists), MegaTones (instrumental versions of songs), and wallpapers quickly, as well as stay connected via the Web, instant messaging, and e-mail.
Under the hood, the Dash features 23 MB of built-in flash memory, a memory card slot for more memory, and a speedy 200 MHz OMAP 850 processor. Up front, the large 2.4-inch 320 x 240 QVGA touch-screen supports over 65,000 colors, while the rear of the device houses the 1.3-megapixel camera. The design of the Dash is clean and uncluttered, with most of the buttons easily accessible with one hand. Just to the right side of the display you'll find convenient up/down keys for volume adjustment and handy keys for browser control. There's also a handy HTC JOGGR control pad with variable speed, drag, and hold functions that makes document viewing a pleasure. Meanwhile, call answer and end buttons surround a five-way toggle that allows you to navigate and control the Windows Mobile interface. A full QWERTY keyboard resides underneath the large display. As mentioned earlier, a microSD memory expansion card slot is provided, and USB/Bluetooth connectivity is included for convenient data transfers.
The Dash's phone and PDA functions are designed to provide an integrated, seamless experience. The included Microsoft Windows Mobile 5.0 Smartphone software with Direct Push technology gives you instant access to your e-mails, calendar, and contacts at anytime. That means wherever and whenever, you'll be connected. 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 Dash features all the functionality folks expect from an advanced cell phone, including a hands-free speakerphone, polyphonic ringtones, a vibrate mode, and picture and ringer ID. Microsoft Office Outlook Mobile combines e-mail, calendar, contacts, tasks, and notes into a single application that seamlessly integrates with the Dash's phone functions. Meanwhile, headsets, car kits and other wireless peripherals can also be paired with the unit via Bluetooth.
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 Dash.
Like all T-Mobile phones, the Dash supports voice-mail, caller ID, conference calling, call forwarding, call waiting, call hold, built-in paging, and access to T-Mobile's 411 service.

Plus, the inclusion of Wi-Fi (802.11 b/g) in the Dash allows you to surf the Web or check your e-mail 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 Dash is Microsoft ActiveSync, which allows you to quickly synchronize your device's tasks, calendars, e-mail, 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.
Another great feature of the Dash 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. You can also keep favorite tunes loaded on a memory card and listen to your music wherever you roam.
The Dash can take 1.3-megapixel 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.
