I have this application which is called "Caller ID Faker" and I had it for a while, and still do. It does not seem to be in the android market anymore, but at the time, I downloaded thousands of android .apk's off a torrent. It still works, but you can use it up to three times a day and the calls last for only two minutes, but of course one would have to purchase more minutes for longer conversations. What the application does is allows one to make a phone call to anyone using any phone number you wish the receiver to see.
I just really want to create my own version of it, but I have not Google to deep into that which I am eventually. I tried looking for some open source codes just to get me started, but have not had any luck. So I created a basic application, but all it does is ask for input of the callers number and just hit the call button to call lol.
Does anyone have information with spoofing calls?
