Random Ringtone Generator

Last night I was playing with my phone realizing I can easily connect it to my laptop. This enabled near instantaneous file transfers. Then I noticed I could put ringtones on my phone this way.

I'd like to make a python program that connects to my cellphone whenever I'm home and uploads different ringtones every day. Today I could have Moby tomorrow Brittney Spears. This would make me so excited to receive a new phone call!
