B4: iOS 4 Support

It's a strange fact, but a significant number of people (~70%) never update their iPhones, etc. to the latest iOS version. This hits developers the hardest: your app has to be forwards and backwards compatible. For BustIt, we've always tried hard to support our current user base and adopt the latest technologies.

We have added Twitter support to BustIt 4, but these features are lost in iOS 4. We've spent the better part of 2 days trying to find some sort of compromise, and we've had to scrap the concept (unfortunately). So you will be left with email and Facebook support for sharing...
