With a dev license you can install pretty much anything on your device through XCode. And if you do not want to compile but wanna collaborate on the project, we offer the possibility to become a tester of our RAW branch :)
It's actually quite easy. You open up the project in Xcode, plug your telephone in and select it as the build-target. Then you click "run" and fix all the problems that come up. You need a Team (you AppleId will suffice), you need to change the bundle-name because the current name is of course owned by another team (the blink shell team). You can change it to something random like com.idontcare123.Blink. Click run again and the App will magically appear on your device.
