Is it possible to disable Spark on iPhone from defaulting to Video when you are not on wifi. I was in the car the other day when I had a spark call, I answered using the cars hands free and it went into a video call. This made it very difficult to interact as the quality was poor due to the bandwidth being used, also I don't want Spark to hammer my data allowance and as I was driving it was not posable to interact with the phone to disable video.
