Since the dawn of Android smartphones with huge 4 and 5-inch screens, there have been rumors that Apple would update their flagship smartphone with a larger display. The rumors were most prevalent concerning the update to the iPhone 4, but they were proved untrue when Apple released the iPhone 4S.
Now, a source has come foreword with what may be some more credible evidence of a larger iPhone screen for the next Apple device. According to a tipster from Asia, Japan Display alliance members Hitachi and Sony are producing displays for two next-generation Apple products. Of the two, the source mentioned specifically that one was for the iPad 3, but did not know what device the 4-inch display he saw was for.
If the 4-inch display is indeed headed to Apple, I would guess that both the iPhone and the iPod touch would get the new larger display, as they have traditionally kept the devices very similar. Of course, they have also traditionally kept the displays on these devices small. Many think this is because the average reach of a thumb when using a smartphone one-handed just covers a 3.5-inch display, but some users and reviewers also tout the 4-inch display as the best balance of size and usability.
There is really no telling whether Apple will begin using larger displays in its iPhones, but with current competition heating up some would consider it necessary. Do you think Tim Cook will keep the iPhone and iPod true to Steve Job's wishes, or will he bend to public will and add a larger display?[Electronista]
