AT&T and HTC have unveiled Tilt 2 and PURE smartphones with Windows Mobile 6.5, which deliver an enhanced TouchFLO 3D interface on a large touch screen that makes navigation intuitive and enables access to web browsing.

Both devices provide full access to voice, text, or email in a single contact view, which can be accessed from the contact card or in the in-call screen during a phone conversation.

According to AT&T, the new HTC Tilt 2, designed for business professional, features a 3.6-inch widescreen WVGA display which can be tilted for expanded viewing area, QWERTY keyboard, and a 3.2 megapixel camera. The HTC’s Straight Talk allows for simplified conference calling and activation of the speakerphone.

The HTC PURE, leveraging the TouchFLO 3D experience, comes with 3.2-inch WVGA touch screen, 5 megapixel auto-focus camera, expandable memory, gravity sensor and an ambient light sensor, the company said.

AT&T said that it will also support Windows Marketplace for Mobile in 2009 for access to a variety of applications on new AT&T devices, including the HTC PURE and HTC Tilt 2.

Jason Mackenzie, vice president of HTC America, said: The HTC Tilt 2 and HTC PURE are not only powerhouse devices, they also provide a natural simplicity in the way we communicate with the people in our lives whether through voice, text or email. Our desire is to put people at the center of every mobile experience, and we are pleased to work with AT&T, who shares this common vision.

The HTC PURE is available for $149.99 and the HTC Tilt 2 is expected to be available in the following weeks for $299.99. Small business customers also can subscribe to AT&T’s new BusinessTalk voice plans, which start at $60 per month for five users and 700 anytime minutes.
