Will I be able to upgrade to iOS 7 on iPod Touch 4G? I bought an iPod touch 4G and I'm looking forward to iOS 7... until I read on this site that it is only compatible with the iPod Touch 5G. Does that mean that I'm "Out in the woods" for security? Or does this just mean I don't get the new Airdrop, iTunes Radio, and camera filters?

I don't mind that much that I don't get the new look (although if I could, it would be nice), but I just want my device to be secure.

The thing that I don't get about this is Apple supported the iPhone 3GS up until now (It is three models old), but when another device is one model old, "No! We can't support this device!" Apple could be changing it's views on how to run their business so they make more money, but I like my iPod Touch just fine. In fact, I like the older design better and I can't see running out to the store to spend 300 bucks to get a design I don't like as much just to have a security upgrade.
Towards the end of the WWDC keynote, Craig&nbsp;Federighi showed a slide listing the devices on which iOS&nbsp;7 would be supported. In the official keynote video, this occurs around the 1:54&nbsp;mark.

Here’s a picture of the slide:



It reads:


  iPhone 4 and later
  iPad 2 and later
  iPad mini
  iPod touch (5th generation)


This matches the images and descriptions on the pages for iOS&nbsp;7 for Apple’s website, so this seems to be the canonical list.

It’s possible that Apple will add support for the 4th&nbsp;generation iPod&nbsp;touch between now and the release, but currently it looks like you won’t be able to upgrade.
