I got my TreoPro flashed to MetroPCS, I have Web and MMS but I cannot change the 'default' connection in Connections/Setting, it doesn't allow me to change even the username nor the proxy settings, and in the advanced tab, It keep selecting PowerVision as the default internet connection, so when a program (for example: Google Maps) try to connect to the internet it uses PowerVision. It's annoying!

I can use some help.
