Android manifest for every device

Hi guys, I’ve made a simple game for the android market, problem is not every device can download the game because the manifest force to have Input.multitouch (I suppose)
but the game work fine without it, can somebody tell me how to change the manifest to make the game downloadable for every device?
I didn’t find any modified manifest in the forum

Not sure if this will help, but it seems like this person had a possible solution.
