Art on iphone 5

anyone here have an experience to share? I am thinking about building (my friends told me that it's way overdue since I came up with this idea over a year ago!) and I am curious, since I cannot find this info! about app designs on multiple phones. Like if i have a app built (for iphone 3Gs or 4 lets say) and I want to also have the app shown on the new iphone 5 which has a bigger screen do I need to remake all my art again?? I dont understand how art designers do this any help appreciated and have a good night.

Scott,

To put it briefly, yes; for the most part, artwork that was designed for apps for iPhone 4 and earlier aren't going to fit exactly on the iPhone 5 screen, which is a little larger than earlier models. The app will still function, mind you; it's just that the artwork will look a little "off" on the bigger screen.
