AT&T’s very first LTE-capable tablet, the HTC Puccini, just posed for the cameras. Engadget got the photos from an anonymous tipster who emailed them.

Engadget‘s source claims that the tablet is currently still being tested. The source also confirmed that the tablet will be getting a 1.5-GHz dual-core processor, 1 GB of RAM, Android 3.x Honeycomb, 16 GB of internal storage, and WXGA-resolution 10.1-inch touchscreen.

Earlier reports say that the HTC Puccini’s processor will be a Qualcomm Snapdragon MSM8660, one of the dual-core processors that version 3.2 of Android Honeycomb supports. So, it is also likely for Android 3.2 Honeycomb to be onboard. The tablet’s display resolution is said to be 1280×800.

A Pocketnow report says that AT&T will be rebranding the HTC Puccini into the HTC Jetstream when the tablet is released on the AT&T network. The same report also points to the possibility of an entirely different name for the tablet’s international version.

HTC’s financial officer, Winston Yung, confirmed recently that the HTC Puccini will be launched either in late September or early October. It is possible that HTC will launch the HTC Puccini (HTC Jetstream) at an upcoming media event slated for September 1.

Documents filed by HTC at the Federal Communications Commission (FCC) showed a device with model number PG09410, said to be the HTC Puccini (HTC Jetstream). FCC technical reports for the device also point to GSM, WCDMA, and LTE radios that strongly suggest–if not confirm–that the Puccini/Jetstream is heading to AT&T.

User interface screenshots leaked earlier suggested support for stylus-based input (HTC Scribe) and HTC’s custom UI, HTC Sense. The new photos from Engadget, however, do not show the pen icon on the user interface. This probably indicates that the HTC Puccini won’t be having PenScribe support, contrary to earlier rumors.
