I have a BB Curve 9300 and I am unable too download music onto my phone. It downloads 18 seconds of the song and then when I play it, it says 'unsupported file format'. I know people on the MTN network and they do not experience this problem. Vodacom, however, is the only network that does this as I know a lot of other people that are experiencing this same problem. Does anyone know how too fix this?
