YouStash
YouStash - Now you can finally download and cache videos from YouTube on your iPhone/iPod Touch!
Do you want to watch some YouTube videos later, when you won't have an active internet connection? Download them and save them in your cache, and then you can watch them even when you aren't connected to the internet!
You can find videos by searching for a title, looking through the Featured, Most Watched, and Top Rated categories, or even search by the video's URL or video ID!
YouStash even lets you pause and resume videos, so if you have to exit the app or if you lose your connection while downloading, you can resume right where you left off!
