Donna, got an idea for you! You wear jeans. Jeans have belt LOOPS. Make a little tether - okay, take a piece of yarn, loop it around the middle of the cell phone and tie a knot. Reinforce it staying with a piece of pretty tape to tape the yarn to the back of the phone. Now cut the yarn long enough for the phone to be useable while still tether to your belt loop. Tie a jingle bell on the end of the yarn, and then tie the "bell end" to you belt loop each morning, and stuff the rest of the yarn and phone into your pocket. Why a jingle bell? Two reasons: A. Jingle bells are always appropriate in fashion, right?
B. If the yarn manages to come untied, and the phone falls out of your pocket, the jingle bell will jingle when it hits the floor, saying "Donna! I fell!"
