Apple's iPhone 5 goes on sale Friday, including a polished new look. But only one new feature actually matters: Its super-fast LTE wireless connection. With Internet access that's amazingly quicker than before, mobile computers like the iPhone 5 can finally live up to their promise.
What's LTE?
Simply put: It's the latest version of wireless network technology, used in the U.S. by Verizon Wireless, AT&T, and more recently, Sprint. LTE has been around for a couple of years, and Apple included it in this year's new iPad. (That's how I know firsthand how amazing it is.)
