AT&T just announced at its Developer Summit two LTE phones that will cost less than $50 on contract. First up is the Pantech Burst, which will have a 4-inch Super AMOLED screen, and comes in either black or red. There's also the Samsung Exhilarate, which is being described as the first "sustainable" LTE device. AT&T says the phone is constructed from 80 percent recycled post-consumer materials, and it has an Eco calendar and calculator to help you figure out how green (or not) you are.

You'll be able to purchase the Pantech Burst alongside the Element tablet (which was also announced today) for $249.99 if you buy a contract for both devices. Clearly, AT&T is looking to lower the price of entry and get more people on its expanding LTE network. We think $50 is certainly a reasonable price for access to LTE, though don't forget you'll be saddled with that two-year contract. We should have more details on both phones soon, and we'll be getting some hands-on impressions after AT&T's event finishes up.
