All carrier maps completely refreshed and updated for the entire USA. AT&T, Sprint and T-Mobile all continue to turn on new LTE markets, while Verizon seems to be slowing down. We continue to manually mark T-Mobile LTE markets with a purple star, as their own maps don't visually make a distinction between 3G/HSPA+/LTE at regional zoom levels. 4G Finder has also been optimized for the new 64-bit A7 processors found in the iPhone 5S, iPad Air and Retina iPad Mini. As usual, your reviews in the App Store and telling your friends about the Coverage? line of apps (including 4G Finder & LTE Finder) help us reach new customers. These free & frequent map updates are entirely funded by new sales of the full version of this app - Coverage?. We greatly appreciate your support & enthusiasm!
