How many iPhones can I put my apps on?

[nlivo]

I have bought a few apps on iTunes through one account. I have more than one iPhone in my house. How many iPhones can I put them on? Is there some sort of DRM on them?

You can sync the apps to all of the iPhones / iPod Touches that are synced through the same installation of iTunes.

Just log into your itunes account on up to 4 OTHER computers in your household and they will be able to share your apps as well.

Remember to authorise the computer.

Anyone know where one can find instructions as to how to do this?

EDIT: NEVERMIND. I think I need to authorize something. Might've figured it out.
