With the application of a knife along the seam on the side and top of the device, the use of tweezers to hold the newly-formed gap open, the use of another pair of tweezers to reach in and grab the antenna, and the replacing of the rubber insulating plug on the side of the iTrip to seal the casing back up, I was able to fully extend the antenna out the side of the iTrip at a healthy 90º angle with almost no scarring of the case.
