At its press event today, Apple announced the new iPhone 5 with a 4-inch, Retina display. For customers, the larger screen means there's extra room for apps to display their content. The most noticeable difference will be the homescreen, which will now display five rows of icons.
This extra screen real estate allows built-in apps like the calendar to display the full five-day work week. Other apps like iPhoto, iMovie, Keynote, GarageBand, Pages and Numbers will also be updated to support the new screen.
