Sorry guys if this seems like a stupid question but I havnt really bought apps before, i normally just get free apps. Recently I bought abouts £30 of apps for my ipad and i have them all backed up to itunes on my macbook. My question is... If your macbook were the break down... (il use mirrors edge as an example) and I lose all my apps.... that were in itunes.. and I deleted mirrors edge off my iPad... Would I then have to re purchase it? or will iTunes remember I bought it already?
