Make it lighter and thinner, this is the formula that has been at the core of product iteration at Apple and looks like the new iPhone 5 will not be any different.
A set of leaked photos by Nowhereelse.fr show a comparison of the new iPhone with the iPhone 4/4S and the iPhone 3GS. The only interesting bit in these photos is the noticeable thickness difference of the new iPhone as compared to all the older versions.
We are not really sure if thinness alone would help gain traction in the market but we will give Apple a benefit of doubt till they actually release the new iPhone, hopefully this month.
