I downloaded this app on my Incredible within a week of getting my phone. This app gives you the ability to call anybody and fake the number that shows up on their caller i.d. Just think of the possibilities! Unlimited calls, the only downfall is they are limited to two minutes but you can easily call back! Your able to change your voice to a woman or man and even record the call! Email will be sent with recorded calls or you can download them on your phone. This App is simply amazing and it's FREE!!! I prank called a friend who hasn't showed up to the DZ in a while. Called them from our Skydive Dropzone number and he answered. Told him that since he was in the Army they were giving away free jumps to military members. He said he would be there on Saturday. He shows up and asks about free jumps and we all laugh. All of us there actively serving in the Army did a Memorial Day Jump!!! Was great to have him there. And that's just one way this app can be used for good! You could just have a blast sitting there prank calling people too! Must Download App! Just be prepared to have time on your hands because you will be thinking of people that you can prank call!
