Hi, Does anyone know of an armband that a Motorola Droid X in an Otterbox defender case will fit inside? I want to use this for running and the clip on outer plastic shell of the Otterbox case is not sufficient. The phone bounces around too much. Anyway, I don't want to remove the otterbox every time I go run. I would greatly appreciate anyone that knows of an armband that would accomidate the size of the Otterbox Defender case. Thank you very much.
