First of all, welcome to Macrumors! Most of us love you here.
Okay, do you have a laptop where you can test where you get WiFi in your house? The iPhone's chip is a little weaker, but shouldn't be that much weaker.
T-Mobile and AT&T use different 3G frequencies.
AT&T uses 850 and 1900, while T-Mobile uses 1700/2100.
T-Mobile USA is the only provider in the world to use those frequencies, so only phones made for T-Mobile USA can be used on their 3G frequencies.
Thus, the iPhone 3G cannot use 3G internet on T-Mobile's network.
