The two devices — the USBConnect Momentum 4G and AT&T Mobile Hotspot Elevate 4G — will be able to access the company’s network when the network goes live. Until then, the devices will be running on AT&T’s HSPA + network.

The Momentum 4G will be $49.99, and the Elevate will be $69.99, and will require a $50 data plan that comes with 5GB. If you overshoot your cap, it will put you out $10 per extra gigabyte.

If you already own the USBConnect Adrenaline, you can download a firmware update to make you LTE ready on Aug. 26.

The first five markets for LTE are Atlanta, Chicago, Dallas, Houston, and San Antonio. AT&T has said that it will add 10 more LTE markets by the end of 2011.

AT&T has also announced that a 4G version of the HP TouchPad will be available in time for “back to school” weeks — so they’d better hurry.
