For iPhone owners worried that they are set to lose a host of their favorite standard and in-built apps, there is nothing to fear -- the weather, stocks, note-taking, reminders and compass apps are all still present and correct, they've simply undergone a visual facelift.
Steve Jobs was a big fan of skeuomorphism -- making virtual objects appear like real three-dimensional objects -- partially because he saw it as a way of helping the uninitiated understand how a feature, setting or app worked, and what it was for. That's why the notes app looks like a yellow legal pad and why the compass, when launched looks like it has come from a ship.
But both the iPhone and its interface are six years old and the smartphone is no longer an emerging technology. And, with iOS7, the iPhone now once again looks and feels as fresh as it did back in 2007 when it was first unveiled.
