hi, if you have jailbroken iPhone, you should install Firewall iP (on cydia) and when the app tries to request access from the net just block it, or if you have not jailbreak, just disable 3g data, and works, sadly when using the app, you will have not net acess, unless you try to unlock with a .unl file via jetmouse keygen, puttin your unit id showed on settings -- general -- about--....

newest version is USA-v2.1.07-FAULTYCLONES I needed to lock net access with cydia firewall ip (does come with usa map, and it is locked) so, remove the maps with ifunbox locating the folder, and if the map is locked try to unlock it with gimgunlock, its fast and easier than ever....
