Where do you put your phone when riding?

The inner tube bag is large. There is a top bag. There is an arm band. The Daylite Pack was made by the Osprey. There is a Camelbak. The Topeak Large Aero Pack is large. There are pocket pants. Most people don't carry a cell phone in their pocket. There is a Jersey pocket. One of those pockets on the back of a cycling jersey is the most common place to put your cell phone.
