i can upload my mp3s fine, then go to the wap site on my BB 8700v, find the download link fine but then i get an Http Error 503: Service unavailable.

does anyone know of a reliable alternative?

funformobile.com is one that i've used. you upload files and they send a text to a link where you can download the ringer. you can also just go to your uploaded ringtones manually and download them from there. I still find that sending them to a gmail account and logging in from the BB and downloading them there to be the easiest.
