The first HTC tablet to market running Android 3.1 will be the HTC Jetstream, HTC and AT&T announced today. Landing in stores next week, the 10-inch tablet will be able to use AT&T's 4G LTE network at launch, and while its specs are impressive, the form factor and price are less so.

The Jetstream has a 1.5GHz dual-core processor, 10-inch 1280x768 resolution screen, an 8-megapixel camera on the back, and a 1.3-megapixel camera on the front. The 32GB onboard storage can be supplemented by 32GB more via microSD, and the Android 3.1 Honeycomb operating system will be skinned with HTC's Sense.

However, the body of the Jetstream is unimpressive-sounding: it measures over half an inch thick (0.51 inches, to be exact), and weighs 1.56 pounds, just an ounce less than the HP TouchPad and a few more than the iPad 2. No WiFi version of the tablet has been announced, so there's only the 4G LTE version, which is priced at $699.99 with a two-year contract.

With the Jetstream, AT&T is introducing a new data plan for tablet customers with contracts. In addition to the $15/250MB and $25/2GB per month plans, customers will now have a $35/3GB per month option if they are on a contract—prepayers need not apply. Off contract, the 32GB Jetstream costs $849.99.

The HTC Jetstream will be available to order online or purchase in stores starting September 4, and will be bundled with the HTC Scribe pen "for a limited time."
