Me and my brother each have iphones. I have had mine since the 2g release and he just got his recently. I have a ton of apps and he has a few new ones i do not have. He is at college. We waould like to share each tohers apps so we only have to pay for one for the 2 of us. I know with songs you can activate it on 5 different computers does this work the same with apps and if i just drag the icon into a email will he be able to use it? also will it delete his other purchases if he puts it on?
