Harry Potter iPhone Book Downloads
Unfortunately, you can't get Harry Potter books on your iPhone or iPad, or for any kind of eBook format. The reason is that author JK Rowling (or her publisher) had previously opposed the electronic format. I have read in this May 2010 article on TheBookSeller.com that Rowling is now looking into publishing the Harry Potter books for eReaders, but as of this writing they are not currently available through legal channels. For that reason, I don't recommend trying to download Harry Potter books from any outside or unfamiliar sources because they will be illegal copies that violate the copyright.
Since the actual seven Harry Potter books are not currently available in eBook format, there are other Potter-related books available. To get the other books like guides and trivia books, you have two options. First, you can download the free iBooks app that works as a virtual bookshelf where you can purchase and download books right to your iPhone or iPad. Your second option would be to get the free Kindle app from Amazon.com that lets you purchase books from the Amazon Kindle Store. It also works as a virtual bookshelf and lets you download books.
The iBooks app looks like a virtual bookshelf, as seen in the screenshot here. You must first install the app before you can search the bookstore, which I find to be kind of annoying. The Amazon Kindle app is not required to search the Kindle bookstore because you can just use your web browser. I had to install the iBooks app before I could find out there were no Harry Potter books on there. They have a bunch of ebooks related to the Harry Potter series, but none of the official novels. I had to download and install an app, then use its clunky interface before I could figure that out.
You can get a lot of free classic works through iBooks or the Kindle store, so it may be worth at least installing the software and getting familiar with the interface for when the Harry Potter books do finally become available in electronic format. All of the Potter books are going to be reprinted with new jacket designs once the last movie comes out.
