I bought an app.. and I made a mistake and i just erase it!!.. if I want to download the same app again.. why i have to pay again for the app?..
You can download the same App for no charge.
You can download it again from appstore free of charge but when you open that app instead of download there will be written install. Just click install and app will download.
Downloading past purchases from the App Store, iBookstore, and iTunes Store
