AT&T nabs One X+, One VX, Windows Phone 8X from HTC

AT&T said today that it would add three more HTC smartphones to its lineup, the HTC One X+, One VX, and Windows Phone 8X.

Windows Phone 8X, which was announced last month, will be available in November, while the One X+ and One VX would be available "in the coming months." No pricing information was provided on the phones.

The announcements are just the latest from AT&T, which has been bulking up its smartphone lineup for the holiday season. In addition to the iPhone 5, which launched last month, the carrier has announced phones and tablets from Samsung Electronics and Sony. Today's phones are just the latest expected to be announced by a U.S. carrier in the coming weeks.

The HTC One X+ and One VX will be exclusive to AT&T. The One X+ is the quad-core equivalent to the One X, which was also an AT&T exclusive launched earlier this year. HTC announced a global version of the phone earlier today.

Previously, the One X was either quad-core and 3G, or duo-core and 4G LTE. The One X+ offers the best of both options, and comes with Android 4.1, also known as Jelly Bean. It also features longer battery life and more internal storage at 64 gigabytes.

The One VX, meanwhile, is a mass-market Android pone expected to be lower priced than the One X+ The phone has a unibody case and is 9.19 millimeters thick. It features a 4.5-inch Gorilla Glass display and a 5-megapixel camera able to take still images from a video with HTC's VideoPic feature.

AT&T is the first U.S. carrier to commit to selling the Windows Phone 8X, which is Microsoft's flagship mobile product this holiday season. But AT&T isn't going to be the last. Verizon Wireless and T-Mobile USA are expected to sell either this phone or the Windows Phone 8S this holiday.
