It's pretty much a sure bet that the next iPhone will support LTE-based 4G, but what Apple lovers really want to know is if it will support worldwide 4G. According to those always wily "people familiar with the matter" and the Wall Street Journal, the iPhone 5 will be able to reach 4G speeds in parts of Asia and Europe as well. The WSJ's source did not outline any specific countries, but did add that the next generation iPhone "isn't likely to work with all carriers' LTE networks in all countries, though it wasn't clear which would be left out."
Apple's first device to offer 4G LTE was the iPad 3, however, it is only supported by Verizon Wireless and AT&T in the U.S., and Bell Canada, Rogers Communications and Telus Corp. in Canada. Major U.S. carriers such as Sprint and T-Mobile have been pushing hard to extend their 4G LTE networks, and it's estimated that worldwide 4G LTE will reach around 290 million people by 2015.
Apple is expected to announce the iPhone 5 at a press event in San Francisco on Sept. 12. The next generation iPhone is expected to feature 4G LTE, a larger screen and be the first Apple device to feature a nanoSIM and a smaller dock connector.
