I know someone was asking about some phone before (nice and specific there, huh?)...anyway. Anyone know of a way to upload ringtones to a motorola razr phone via bluetooth?

Just don't want to buy ringtones and stuff since it;s a ripoff and the basic ones aren't the best. Also would like to see if I can upload java app games and stuff (not that I play em often on my phones, but now and then). Thoughts?
