Syncing ipad2 and iphone4?

[Catering10]

I have done what I learned on You tube to bump my iPhone4 and my iphone2, though when I go on to the bumped app it asks me to download, is this correct? Will I have to pay for this app again? Or am I doing something wrong?

Please help

You will not have to pay for the app again if both your iPhone and iPad have the same iTunes account. However, some apps are universal - they'll run on both the iPad and iPhone and will automatically adjust to the screen size and resolution - others are iPhone apps and will run on the iPad, but without adjusting to the iPad screen and others are iPad specific and will not run on the iPhone.
