Looking for a Y connector, do they exist?

[JDBreeze1]

I have my sync cable that came with the Storm, and I also have the charger cable that I plug into the wall. Sinc emy computer isn't on often enough to rely on it as a charger, I have my Storm in a dock which is connected to the wall charger. But then I can't sync unless I unplug the wall charger from the back of the dock and plug in the sync cable.

What I'd like to get is a connector where I could plug both the sync cable and the wall charger in, and then I could connect it to the Storm or to my dock. A micro-USB Y-connector, if you will. Basically I'm looking for the opposite of this. Does anything like this exist?

Could use Bluetooth to sync and leave the wall charger plugged in. I have not seen any mini USB y connectors. But then again I have never looked.

In other words, double female to a male micro USB connector?
Radio Shack should have them. That's who I would contact.
