LG hasn’t launched a Windows Phone in the United States since it began offering the LG Quantum on AT&T over a year ago. That may change soon now that an image of a device dubbed the “LG Fantasy” has been leaked running Windows Phone, however. Little is known about the Fantasy, though rumors suggest it has a 4-inch IPS display. The leaked image of the device is blurry, but we can see that the phone either has a 5-megapixel or 8-megapixel camera, which is in line with what the current batch of Windows Phone 7.5 (Mango) devices offer. It’s unclear if the phone will ever make a U.S. debut, but rumor has it the Fantasy is scheduled to launch sometime next year. Perhaps we’ll hear a bit more about it during the Consumer Electronics Show in Las Vegas next month.
