With the new iPad breaking sales records, the rumor patrol is already on alert on Apple's other widely popular device: the iPhone.
Reuters reports Apple's new iPhone will have a sharper "retina" display and have a much larger 4.6-inch screen. The most current iPhones have a 3.5-inch display.
The new iPhone is set to be launched around the second quarter, according to a report obtained by Reuters in the South Korea's Maeil Business Newspaper.
A 4.6-inch display would put the iPhone in direct competition with the Samsung Galaxy Nexus , which has a 4.65-inch screen.
According to Reuters, Apple has already placed orders with its suppliers for the 4.6 inch screens.
