Speaker dock for other smartphones?

[jacquiH67]

I love the look of some of the Sony Radio and speaker docks and would love to have one in my kitchen but i dont have an Iphone i have a samsung galaxy s2.  Why do Sony and other companies not do a clip in adapter to the docks which can be used for phones with mini usb which is the non-iphone standard connector?

If anyone knows of any please let me know?

Thanks
