If you want to revise, there are a number of Laws lessons that are available as a Podcast/AudioBook and which can be played on a computer (via Quicktime or iTunes) or on an iPhone/ iPod Touch.  To use on an iPhone/iPod Touch you first need to download the file and open up in iTunes. When you next sync your iPhone/iPod Touch you should be able to find in AudioBooks/Podcasts.

You may choose to establish a personal iTunes account to add applications (if you do so they will remain within your iTunes account) to your iPod Touch. If so, you can find some useful student iPhone/iPod Touch Education applications here. See also the Flashcards study helper. It is also possible to download books and read on the iPod Touch (search for 'Stanza' in the iTunes Store).
