I realize this is an old thread, but I have a similar question.
I have an iPod touch 4g which can't go past iOS 6. The current version of RasPiConnect seems to need iOS7, but iTunes downloaded the "latest compatible version" for iOS6. This is RasPiConnect version 2.37002140. Unfortunately, soon after is opens, it will crash.
Anyone else running RasPiConnect on iOS6 or any chance of another version that will work with with latest iOS6 (6.1.6)?
