It's bad mmkay.

You will need a jailbroken device running ios 5 or below
Add the following repo:

Search for Iap free
Install and respring

Open the app and tap on the random udid button. This is to make sure the developers do not find out the identity of your device.

For those on ios 5.1.1 you are going to need an extra app
seaarch for udid faker and install
You will note that iapfree does not open when you tap on it which is okay.
Open udid faker and change your udid for the specific app you want.
