Default [Q] wap.voicestream.com

Out of curiosity how do I manage to find out all the information for the access points for T-Mobile? I have my 3G and everything set up but I lose connection from time to time and I have to go over and switch to Wi-Fi. I currently have the HD2 and I am running the Energy Froyostone v2


Will this help out my T-Mo US connection from dropping here and there?
