I've written an app that allows you to set the ringtone ...on someone else's phone. You can even record a "ringtone" straight from your microphone that will then play on their phone the next time you ring it.
I'm looking for people to help me test it ... or just use it and tell me how you get on.
The app is called "tonepush" for Android. You can get it here on the google play store : https://play.google.com/store/apps/details?...onepush.android
Let me know how you get on with it.
Sorry that there's only xmas music at the moment. If it takes off, I'll plough cash into licensing more ringtones. But the "record your own" is completely unrestricted. Have fun.
