Lately I've been having a problem being able to redownload apps from my iPod touch in the app store. I usually check to see if I already own it by writing a review on the app from my iPod and if I can I know that I purchased it already so then I re-download it on my iPod. But lately apps that I know I bought before I can't write a review on if I don't have it installed on my iPod like before so I am hesistant on clicking the buy now button so I don't get a double charge of the same app. Anyone have this issue besides me?
