i am about to unlock a brand new treo 750 from cingular so i can use it with tmobile. anyone know if it will allow me to use mp3s as ringers or is this one of the features cingular blocks? on that note, what will i not be able to use and is there a way to debrand the 750 as of yet? thanks
ps anyone ever used one of these unlocking methods off of ebay? success, garbage?
