If you back up your device to a computer or the cloud before performing a update you can always restore the device to the backed up version, if you don't back up then you are stuck with the update.

 

Apple keeps a copy of the previous iOS version on line for a couple of weeks after a release. I downloaded it, reset my iPod and installed. I was a pain. Looks like people have it going so I’ll try the update again.
