There are rumors flying of an Apple device similar to the iPhone 5S in dimension, however running the hardware from the iPhone 6, but crucially with a 4 inch screen. The iPhones have been a runaway success, slated to sell over 70 million pieces, and the 4.7 and 5.5 inch versions have been well received. However it looks like Apple is looking at a regular sized 4 inch display model as well. This in my opinion is a welcome move. I like the iPhone 6, but it's just not as easy to handle as the 5s. If Apple can pack the same hardware + decent battery life into a 5S form factor, it would be great. Especially that camera More as I get sources/confirmation.
