I just got my iphone 4 and I has a question. If I buy an application and remove it. Do i have to buy it again or is it saved in my Itunes account? Or is it any other ways I have to get it? Besides Appstore?
No you don't have to pay money again.You can download again from any iPhone or iPod that
using your account for free.Yes you can use your iTunes account on multiple iPhones for example my whole family is using iPhone and same iTunes acc.
