I'm updating our catalog and one of our products is available for the iPad. I'm looking for the log for that. I've found "Made for iPad" but I'd like just simply "iPad".
Apple has published trademark and product placement guidelines. Unless you are a registered developer, you should contact Apple and they can assist with proper logos and artwork.
You'll need to speak directly with Apple's Marketing, PR, and/or Legal departments about this. Just casually throwing around Apple trademarks (or, frankly, any trademarks you don't own) is likely to get you sued.
That said, Apple's PR site has this page has a bunch of product images that appear to be for public consumption.
You should still speak with someone at Apple Corporate about this. To keep a trademark, under US law, a company must defend that trademark to avoid dilution. Don't get yourself and your company or organization on the wrong side of a lawsuit.
