My friend has an iPhone 4 and I have an iPhone 3GS, she has apps which she has purchased with her iTunes and I wanted them. She signed out of my app store and logged in with her email and reloaded the apps she had. I had to push the buy install button but when it started to load it said this application is already purchased do you want to reload and I pushed yes and I got. I was wondering if it still charged me. My dad is worried it did and it's freaking me out. I dot think it did but just making sure! Thanks!
