Details of a new HTC uberphone for AT&T, the HTC Holiday, have emerged, looking to take on the Samsung Infuse 4G with a 4.5-inch touchscreen. According to the info discovered by 911sniper, the HTC Holiday has a 4.5-inch qHD 960 x 540 resolution display and the same 1.2GHz Snapdragon MSM8660 dual-core processor as in the HTC Sensation.

There’s also 1GB of RAM, WiFi b/g/n, Bluetooth 3.0 and twin cameras: 8-megapixels on the back, and 1.3-megapixels up front for video calling. The Holiday will apparently run Android 2.3.4 Gingerbread, though we’re assuming it’ll have lashings of HTC Sense on top too.

Meanwhile, Pocketnow dug up an image purportedly of the handset, suggesting that it will look – face on, at least – much like the HTC Desire HD, with a simple monoblock design with a row of touch-sensitive buttons under the display. Whether it might have AT&T HSPA+ or even LTE remains to be seen.
