Engadget posted a story that Apple may release a LTE-enabled 4G iPhone this year

Earlier this year, Verizon CEO Dan Mead all but confirmed that an LTE Apple device would be making its way to Verizon. Eventually. And no 2011 Apple rumor spattering would be complete without at least a casual mention of the high-speed 4G network. Now, BGR claims to have received an internal iOS test build from a major carrier, revealing a property list file for LTE. This of course doesn't guarantee that Apple will be shipping an LTE iPhone flavor later this year, but that it at least remains a possibility.
