I'm almost positive it won't. Maybe with a different case, but Otterbox is pretty bulky, I'd be surprised if the phone fit into any other case/holster with it on. However, I would not give up your OtterBox for this issue; they are the best case made for a phone, and have saved many a phone of mine from damage or death. Otterbox also has some of the best Customer Service I've ever dealt with.
