I purchased for my mom an ihome ip9 docking station to use with her iphone 4. It’s worked well, but recently she’s purchased an otter box defender case which ultimately has ruled the ihome dock useless as the phone will not fit in the ihome dock with the case on the phone and she’s not all for removing the case every time she wants to use her ihome. So, my question here is: Is there a dock extender that I can use to connect to the iphone 4 allowing me to put the iphone in the dock with the otter box case on?
