So, I "buy" an app... Use it for a while, decide I don't want it on the phone, and delete it.. Some time passes, and I want to use the app again - do I have to buy it again, or does iTunes remember that you bought it, and will let you get it again. I guess on a larger topic, if I get a game for "free", and the the dev starts charging, do you then have to pay for it? Thanks for the help. I admit I have never read the purchasing agreement from iTunes, but I don't speak or understand legaleeze...
itunes remembers and you pay the price that the game lists when you buy it. If you get a game for free and the price rises then anytime you download it the game is free for you
Once you download it once, you won't have to pay for it again. Also, if it's free when you get it, you won't have to pay in future.
if you bought it once it comes up free...if you are unsure try writing a review for it and if it lets you then you can get it for free.
