iPhone, Bose Sounddock + Bose Wireless help!

[dirty boy]

Hi

Hope someone can help please?

I have an iPhone which can stream music to the Bose Wireless via bluetooth or some other wizardry....I also have a Bose Sounddock which we use to charge the phone on.

The second you dock the phone, the sound dock takes over the wireless, ideally, we'd like both to play at the same time so we can have music in the house and at the bottom of the garden.

Any ideas on an App or a solution, so the phone somehow outputs via the connector and bluetooth simultaneously?

Thanks!
