iOS 4: What you need to know

21.06.2010

If there's a bright side, it's that misery loves company: second-generation iPod touches won't support those iOS 4 features as well. Speaking of misery...

Unfortunately, original iPhone and iPod touch models cannot run iOS 4. In the past, Apple has made each iOS upgrade available to all previous generations of each device, but the company has deemed that the newest OS version requires too much overhead for the original iPhone and iPod touch to run it. It's kind of like the line-in-the-sand upgrade you experience whenever Apple updates Mac OS X--sooner or later, an older Mac simply cannot run one of the major OS X upgrades because the software requires more memory or horsepower or introduces new technologies that the hardware cannot support.

You sure will--except you won't be able to do so until later this year. Apple doesn't plan on making iOS 4 run on its tablet until the fall. We'd love to give you a more definitive time frame, but that's as specific as Apple has been. If it's any consolation, iPad owners, that iPhone and iPod touch users will only be able to access now, such as custom Home-screen wallpaper and the ability to open mail attachments in other apps. Those features debuted on the iPad before working their way to the iPhone and iPod touch via iOS 4.
