People, i have a great idea (if i may say so ). Is it posibble or alowed to edit the phone.app? See: I want to make an extra button when phoning and add some extra functions to the call? Is this possible or allowed? Love to hear from you. I'm not a programmer, just someone with a great idea! Or can i, during a call, open an app and pass, for example, sounds through the phone? To add sounds directly to/in that call?
