New concepts imagine the low-cost iPhone in 4 and 4.5-inch variants, multiple colors

iPhoneclub.nl has partnered with concept artist Martin Hajek on this latest round of mock-ups that imagines the much-rumored, low-cost iPhone based on some of the recent rumors floating around. More realistic is the red version, as it includes a 4-inch display, polycarbonate backside, and some of the other rumored changes such as the positioning of ports and openings. We also get a larger 4.5-inch version in blue, which is something most analysts don’t expect to see on an iPhone until at least 2014.
