If you’re dying for AT&T to roll out more bars into your area – so you can actually use the LTE on your iPhone 5 – then you’ll be happy to know that AT&T is activating its 4G LTE services in four new markets across the U.S. today.

According to AT&T’s New Room, the following areas are now covered by AT&T 4G LTE:

The demand for 4G LTE connectivity has never been higher, and companies are pulling all the tricks out the bag to try to fulfil the high demand. Last night, Sprint announced that it has turned on high-speed 4G LTE data in 22 new locations. The announcement was made in a single press release on the U.S. carrier’s website.

T-Mobile USA has confirmed that it will carry the Sony Xperia Z this summer, finally putting an end to all the rumors that have been circulating since the device was spotted back in April. The carrier will become the only provider in the U.S. to offer Sony’s waterproof smartphone, which has been available in Japan and Europe since January.

MetroPCS is now ready to start selling devices that run on T-Mobile’s 3G HSPA+ network, which means this is the beginning of customer migration from MetroPCS to T-Mobile. The migration has begun ahead of schedule, coming just six weeks after the newly-appointed T-Mobile began trading.

AT&T has taken another step to secure its place as the best 4G LTE network in the United States. As of June 21, new and existing GoPhone prepaid users will be able to connect to AT&T’s 4G LTE service.
