I download a program for my pearl called radiobee in which I can lestion to internet streaming stations. There is a downside though....with edge if I use a stream that is cd quality 128kbps, the stream constantly gets broken. If I use a 24kbps that stream is fine. But if I had 3G instead of Edge, would I be able to stream music at 128kbps without getting broken streams?

In all likelyhood, no. Real world 3G seldom delivers theorical speeds. And you'd go through batteries like crazy.
