Another great way to get content to your iPhone/iPad is Dropbox. I was not much for the whole "Cloud Computing" idea... but after working with it a while I have to say it is the best. The free Dropbox account gets you 2 gig of storage, which is a ton of documents and ebooks..... Stanza, Goodreader.... and even iBooks (to a limited degree) work smoothly with it....
Just something to look into
