HTC's upcoming 10-inch tablet has surfaced once again and from the looks of things it could be ready for AT&T's network soon. The successor to the company's first tablet, the HTC Flyer, has just passed FCC certification in the U.S. and with that we now have confirmation that it will support LTE connectivity on the AWS 4 and 17 bands -- which AT&T's upcoming 4G network is expected to use -- as well as 3G on the GSM 850/1900MHz and WCDMA 850/1900MHz bands.

Unfortunately no other hardware details were unveiled in the filing, but previous leaks have pointed to a 10-inch screen with a pixel resolution of 1280x720, a 1.5 GHz Snapdragon MSM8660 dual-core processor, and Android Honeycomb with HTC's Sense UI on top. It's also codenamed "Puccini", presumably after famous Italian composer Giacomo Puccini, which some have taken as an indication that it will focus heavily on media functionality.

AT&T announced in May that it will light up its LTE network in five cities this summer: Atlanta, Chicago, Dallas, Houston and San Antonio. The company aims to offer LTE in at least 15 markets covering a population of 70 million by the end of the year. So far the only compatible products that have been announced are a USB dongle and portable mobile hotspot device. AT&T has yet to announce an LTE-capable phone but it seems that the tablet part is taken care of.
