I recently took a visit to a well know App Store Pirate forum, and stumbled upon a thread about apps phoning home. It turns out, quite a few apps now send personal information from the iPhone to the developer if it detects its been cracked. People who buy the apps that phone home are totally safe, as the code probably won't execute unless the app is cracked and the device is jailbroken. There are members who say they are writing to apple, saying its illegal , and really angry that developers are stealing their info Although I think that there could be some improvement in the app store, like trial periods, I fully support the developers for doing this. What goes around, comes around.
