The Verizon iPhone has unleashed a whole new wave of iPhone users, and basic questions (very good ones) are coming to the fore.
Such as, what do you do when an app gets “stuck” — in other words, it won’t quit. Most iPhone apps are supposed to run in the background, allowing you to work in other apps, but if an app is spinning its wheels, it not only isn’t getting its work done, it’s slowing down the whole device.
Fortunately, it’s easy to “force quit” an iPhone app. As Aron Trimble at The UnOfficial Apple Weblog explains, all you need to do us press and hold the Sleep/Wake button at the top righthand corner of the iPhone. This triggers a sequence that can be used to shut off the device, but you don’t need to go through the complete off-on process to squelch an app. After you press and hold the Sleep/Wake button, you’ll see the red slider appear. As soon as you see it, release the Sleep/Wake button and hold the Home button. You’ll be returned to your Home screen, and the misbehaving app will be off.
