Converting iPhone 4 docking to iPhone 5?

Please help!
I had an iPhone 4 and I got this speaker system which is a Metal Bass by LG. But now I have an iPhone 5, and the plug in on the 5 is anti compatible with the docking made for the 4.Is there some kind of adapter or something I could buy that'll let me plug into my speakers? Or am I just $Cr3wed?

Your choice. No 3 rd party suppliers have them yet, but it won't be long before someone like Belkin brings one out cheaper than Apple.
