Here’s a simple way to add documents to your iPhone. This applies to OSX Leopard but I am sure you can do the same thing somehow in Tiger or even on a PC 😉
1) Open your document in its native app. I wanted to put some Word documents on my phone so I open them in Word.
2) Go to File…Print and choose the PDF button at the bottom. Save the doc as a PDF.
3) Open the PDF in Preview. Save as… and save it as a PNG or other image format.
4) Import it into iPhoto. I created an event called iPhone Documents and then a smart album to hold anything that has the word iPhone (thus the entire event). You could also just create an album and add documents to it whenever you add them to iPhoto.
5) In iTunes set your iPhone to sync that smart album to your iPhone. (I already only sync selected albums as I have too many photos to fit on my phone. One other thing I find useful is syncing the “Last Import” album. When I connect my iPhone it opens iPhoto and I import any photos I have taken. I add them to an existing event if applicable or create a new event. Then I delete the originals from the iPhone. Then iTunes syncs that last import back to the phone using the event name I chose, and if I added them to an existing event, it syncs that entire event back to the phone. Seems like a waste, but I find it very handy. I then have three albums on my phone, the photos I am taking on the phone, the last import and my documents. Nicely organized.)
Done. Now you can view your docs in the photo gallery on the iPhone. The quality is not superb, and text size of 10 will be unreadable, but I think it is cool that you can take docs along if you want. No editing, mind you, at least not ’till this summer when Documents to Go or something like that comes out through the app store, but handy for now.
