I just read that several iPhone apps spy on its users and I'm worried that this affects iPod Touch (4G) users too. Apparently, some apps ("Angry birds" and "Texplus 4" were mentioned) retrieves contact information and sends it "home". Do I need to get worried? Is there anything I can do to prevent apps from "phoning home", retrieving personal information on my iPod whenever I go online? Little snitch comes to mind but as far as I know there's no iPod Touch app version available or anything similar (at least not based on my app-store and web searches).
