Everything you need to know about iOS 7 multitasking: The new card interface, background downloads, timer- and network-coalescing, and more!
The original iPhone came with fantastic multitasking. From the very first demo of the very first iPhone by Steve Jobs in 2007, its ability to fade music out, take a phone call, grab a picture and email it, then return to the phone call, hang up, and fade right back into the music seemed miraculous to the crash-prone competition of the time. Then the App Store happened, and all those third-party apps weren't allowed anywhere near the background. Things changed in 2010 with iOS 4, when streaming music, VoIP, and turn-by-turn navigation were granted persistent access to multitasking, and many other apps were given a few minutes of leeway, and the ability to go to sleep and restart, theoretically, right where they left off. But it wasn't enough. Thanks to some system-side smarts, however, it looks like iOS 7, along with a new interface, will make good on the multitasking promise while at the same time protect battery life and performance. If they can do it, they'll be the first to really nail multitasking on mobile.
