The Wall Street Journal is this morning reporting word from Apple's suppliers that the iPhone maker has placed orders for new iPhone displays, which measure "at least 4 inches diagonally." Production is said to be commencing next month, with the WSJ identifying LG Display, Sharp, and Japan Display Inc. as the three major panel suppliers that Apple is contracting.

A move up from the iPhone's persistent 3.5-inch form factor has started to feel overdue in the current climate of 4.7- and 4.8-inch flagship Android smartphones, so this may finally be a sign of the Cupertino company relenting and giving in to popular demand.

We still wouldn't expect Apple to stray much further than 4 inches with its next iPhone, for reasons of resolution and scaling as much as an understandable reluctance to change the world's best-selling smartphone too much.
