Released for AT&T, the HTC Tilt 2 comes with advanced speakerphone technology, turning any room into a conference room. Flipping the handset over activates a speakerphone similar to those found in corporate boardrooms. Using HTC's Straight Talk technology, the Tilt 2 delivers high-fidelity voice through asymmetric speakers with noise suppression for loud and clear conferencing. The Tilt 2 also runs on Microsoft's Windows Mobile 6.5 Professional platform and HTC's new TouchFLO 3D interface so users can use applications like Office Mobile and Office Mobile Outlook to check email, photos, music and weather. Customers can download more software at Windows Marketplace for Mobile. The Tilt 2 groups conversations into single contact view so voice, text or email histories can be viewed during a phone conversation. Additional features include a 3.6-inch widescreen VGA display with a slide-out QWERTY keyboard, expandable memory, a touch-sensitive zoom bar and gravity, proximity and ambient light sensors.
