The other thing i noticed is that after downloading the 2g/3g status bar app and opening it and choosing 3g instead of dual or 2g I stopped seeing t-mobile automatically switch me over to 1 bar of edge making everything slow to almost not opening.

I think if you let your carrier drop you down to the slowest speed during peak hours they will do it but if you force it to stay on 3g it bypasses that.
