Any ideas what the problem is?

I reset my phone and got everything working except internet. It was working fine before..

I have a K850i and used the sony config for the internet WAP setup. For some reason, when I switch over to 3G, my internet comes up with a message saying "connection failed," but when I'm on EDGE, everything works fine.. except a bit slower.

Any ideas?
