So, I've had an iPod Touch for some time now. I have downloaded a number of Apps and even bought one or two. I'm curious if I will be able to use the Apps that I bought for my iPod Touch on my (forthcoming) iPhone without re-purchasing them. I don't mind un-installing the Apps from the iPod Touch (if necessary), but I'd like to be able to use them on the iPhone without buying them again. Any insight?
