Iphone 5/Ipod Touch 5 Apps Screen?

The thing i'm asking is that the applications that were made for a 3.5 inch screen don't fit on the new Iphone 5 / Ipod Touch 5th Generation Screen because its 4 inch

I heard it has a letterbox (black on top and bottom)

when do you think there will be a solution to most of the apps on the appstore?

if you think there will be a solution for it how long do you think it would take approx?

Well I have an iPhone 5… There are unnoticeable black bars at the top and bottom. Many developers are adding 4" screen support in the coming week(s) so, it isn't really a problem.
