Hopefully you saved the multiple dock adapters that came with the dock. Use the one for the iPod Nano. This holds the 30 pin to lightning adapter FIRMLY in place, to the point that it can hold the iPhone 5 up securely even without any back support. On top of that, it adds enough friction so that you can undock the phone from the adapter without taking the whole adapter with it. Try it! My iHome has gone from a fiddly mess to being usable again!
