About iPhone application crack

It’s a long time, since my first iPhone application is available on the AppStore.

Checking the sales reports and application usage, I see that there’s a BIG difference:
There are more request then AppStore sells.

The Reason: pirated apps.

I think Apple is fully aware of the problem, the it looks like they don’t care.

Just to have an idea of how simple is to crack an iPhone application, read how to do it at the following link; the interesting part is the cracking script….
