There are two sides to “fragmentation,” and while Apple’s iOS 6 software doesn’t necessarily have big negative implications for developers, users with older Apple devices will be missing out on some great new features when iOS 6 is released later this year. Gears are already turning, however, and the iOS developer community is doing its best to bring previous-generation iOS device users all the new features they can.

A simplified solution will undoubtedly emerge in the coming months, but savvy users who just can’t wait can follow the read link for instructions. A pair of videos showing 3D maps running on an iPhone 4 follow below.
