I know that you can download your mp3's on the Pearl, but can you set those mp3s as your ringtone? also, is there a size limit on the mp3 that you're trying to set as your ringtone? I'm contemplating about getting the Blackberry Pearl as my next phone and the mp3 ringtone thing is important to me. if i can't set mp3s as ringtone or if there's a size limit to the mp3s you upload to the pearl then it would be a deal breaker. How's the sound quality on that by the way? is it better than the Sony Ericsson w600?

Thanks for your help!
