i currently have an evo 4g phone with all the bells and whistles. i was going to buy a prepaid phone so i can text people and they wouldnt have my main phone #. Example i want to have my main phone but use the app to text other people and they have a different # come up on their end but can still text me back. I dont want to buy another phone but would like another # to text from. The guy at radio shack told me there are apps that can disguise my number.
