Why you should upgrade your iPhone

Apple released iOS 7 Wednesday, a fully redesigned version of the software that powers the iPhone and the iPad. You can download it now by going to “settings,” then “general,” then “software update.” Or you can wait until later to avoid the rush. Either way, it’s not a bad idea to back up your data first.

The new interface is likely to throw a lot of users for a loop. But it does come with a slew of new and rejiggered features. Some are superficial, like “dynamic wallpapers” that move around as you tilt your device. Others mimic popular features of various third-party apps, like iTunes Radio (a Pandora rival) and the new photo filters for the iOS camera (à la Instagram). And some are functional, like a new Control Center that offers easy access to a few key settings.

In this last category is perhaps the one iOS 7 feature that is practically certain to make users’ lives just a little easier: automatic app updating. The need to manually update apps in every previous edition of iOS was so vexing that even U.S. Sen. John McCain took Tim Cook to task for it in a congressional hearing. “What I really wanted to ask is why the hell I have to keep updating the apps on my iPhone all the time and why you don’t fix that,” McCain grumbled. Cook’s response: “Sir, we’re trying to make them better all the time.” Better slow than never. Upgrade to iOS 7, and you’ll find yourself spending a lot less time upgrading things on your phone or tablet from now on.
