If your business is considering running mobile ad campaigns (or already running them) have a look at a new app from Apple, iAd Gallery. Here, advertisers can browse through the latest mobile ads from some of the top advertisers and innovators in the industry; including American Express, BMW and McDonald's.

Ads can be searched, sorted or simply browsed. Also included are the agencies responsible for each ad. Overall, it's a nice way to keep tabs on what the big agencies and advertisers are doing, and what consumers are being exposed to, in order to help create and plan your next interactive mobile ad, whether on Apple's system or elsewhere.

Those interested in the app will need the iPhone 4.2.6 software update.
