It's not rare to find an in app upgrade for appications on the app store (in app upgrade is another name for in app purchases). Typicaly the apps with an in app upgrade are free apps. By putting in app upgrades on apps it forces the downloader to a split path. Either fork over the money or ignore the in app upgrade to the best you can. Well this app "screensaver" has one high price to enjoy the app to the best.
This the first time I have seen a price this high for an Iad removal. The Dev Liu Jian Jun has hade the app "Screen saver ^_^" version 3.2 on the app store since Dec 17, 2011. What Liu Jian Jun claims the app does is act as an interactive screen saver that has falling snowflakes and a clock on the top part of the screen. The app follows through with what the developer says. The only problem... an iAd pop up on the bottom of the screen(this is screen that the user will see after clicking on the x to remove the iAd).
