go to download.com and get "mp3 cutter" free trial of course, pretty easy app, cut about 30 seconds from ur favorite mp3, once thats done send it to ur krave thru ur email as an attachment the address is

ur#@vzwpix.com, so it would be 1112223333@vzwpix.com, once the text comes in save as ringtone, thats it


video up to 2mb's can be sent as well, unlimited data plans usually is the norm for a smartphone like the krave but check ur plan to make sure, be careful hookin up other ppl my homegirl got a regular phone and she racked up $30 dollars in data charges last month doin this    

here can do all !
