Running iOS 5 build apps on the orignal iPhone, iPod touch and iPhone 3G
With the introduction of the iPhone 3GS Apple made a major switch in processor architecture, they went from armv6 to armv7.
Now that we have all update to Xcode 4 with iOS 5, Apple seems to be of the opinion that you can drop support of the armv6 architecture.
Well this isn’t always the case, especial if you want to keep support for those device that can run iOS 4.*. Luckily there is an easy solutions for this.
