The latest issue of Richard Branson’s iPad magazine, Project, issue 4 is now available for free on the iTunes App Store. Apparently the folks at American Express have decided to sponsor this month’s issue so folks looking for reading material on their iPad can download it for free. It wasn’t mentioned why they decided to sponsor’s this month’s issue, and we’re pretty sure this won’t be the last time that an issue gets sponsored by a company as well. Well either way, we’re not complaining – free content is always good. Head over to the Apple App Store to download the latest issue of Project now.
