At&t is the carrier of this phone. You can get just about any accessory that you can get for all other phones for this phone as well. You can find headphones, blue tooth headsets, covers, protecters and so much more.
I think the HTC Tilt 2, See its specifications below
The HTC 7 Pro with the Windows 7 OS brings a good variety into the cell phone market. On the U.S. Cellular carrier base, the phone offers good, substantial features. The screen has sharp 480-800 resolution and the front panel offers a nice 45-degree angle tilt. A major feature of the phone is the additional capacitive touchscreen keyboard. That, accompanied by a well-laid out QWERTY with good spaces, makes the phone a solid HTC offering.
Motorola backflip definitely
There is the HTC phone from AT&T
Battery life can be an issue with the HTC as with any cell phone. Overall, they are good phones with better than avgerage call quality. As with any phone, I would recomend buying the insurance offered with your carrier to protect yourself.
A kind of intelligent cell phone made by Google corporation.
If the HTC Tilt is also an AT&T phone, then yes. There should be no problem with it.
