The former Apple CEO had reportedly worked closely on the new design of the smartphone before he passed away.
According to Bloomberg, Steve Jobs had left his mark on the successor of the iPhone 4S, before passing away in October.
The development and design of the iPhone 5 began before the official release of the iPhone 4S, when Jobs had already officially left Apple for medical reasons.
The publication writes that Jobs had already anticipated the current market trends regarding the enlargement of screens, and had reportedly taken the steps to switch to a 4-inch display instead of the usual 3.5 inches.
However, the news comes as no surprise as the Apple co-founder was known to be passionate about his work and was often directly involved in product design.
