Motorola KRZR K1m

Per the "tmp" method, i got my 19 second ringtone in and working.

My 19 seconds file wasnt very large to email, however most of my mp3's are very large.. Roughly around 7mb range...

I can reduce them, but not sure what is the largest i can send..

So far over 2mb it has been bounced back..

Curious if someone else already knows this answer.

thanks
