[aerogear-dev] Question about iOS 6

Hello, I just succeed to install and configure a aerogear push server and used it successfully on a android device. The next step is an iOS device, i’ve got the demo app deployed on a ipod 4 with iOS 6.1.2 but it crashed. It looks like you need IOS 7 for the aerogear push library 0.9.1? Is it possible to deploy to IOS 6? Can i use an older version of the library, which one should i use? It it not possible to upgrade the ipod to iOS 7. Regards, René Smits
