input/output multifunction cable for HTC Titan?

[TheShade001]

I have a nifty app that allows me to use my Sprint Mogul as a practice amp(for guitar). I have been looking for a cable that has an input, output and a powersource.

I have seen the HTC multifunction audio cable (YC A200), which is exactly what i need, but I wasn't sure if it would work on the mogul.

Has anyone tried this cable on the mogul?

Or does anyone know of an equivelant?

I, also, saw the HTC 3-in-1 cable. I do not think that is what i need though. I need to have an input to plug my guitar into while listening through the output(headphones).

Any insight would be greatly appreciated!
