Well.. that's a bit odd. My iPod got the 8.0.1 OTA update yesterday, but couldn't install. Now it doesn't see the 8.0.2 update, and still insists on installing the 8.0.1 already downloaded. Looks like I'll need to use iTunes to update when I get home.
Nah all you have to do is hard reset it, then it will show 8.0.2 . i had it downloaded but held off on the installation of 8.0.1 for obvious reasons lol, but i did a hard reset and then it told and showed me i could download iOS 8.0.2
