Hi. I have never developed applications for mobile phones but want to know if what I am trying to embark on is hindered at present by current software/technology.
I want to be able to have a downloadable software app that works on as many phones as possible that can change the ringtone of the the phone at will.
I have heard that Java apps work on 90% of phones but after doing some investigation I believe Java doesn't allow access to such functionality.
Is there a way I can create a software app to change the ringtone?
