How to download iOS 7

Hey Crizle, If you have an iPod 5 connect with your ITunes and tap on update iPod. If you have an iPod 4 or earlier, you don't. iOS 7 requires 512MB of RAM and currently ONLY the iPod 5 has the needed 512MB of RAM, and there is no way to increase the RAM size in an iPod. Hope this helps, Good Luck, Cheers.

If you have an iPod Touch 5th generation, while on WiFi go to Settings > General > Software Update and proceed to update.

If you have the 4th generation or older you cannot update to iOS 7.
