I moved apartments within the same building, and my T-Mobile signal went from 5 bars anywhere in my apartment to only working if I leave it on my back windowsill (and then maxxing out at 2 bars if I'm lucky).
So, I'm wondering, is the TMo's Edge service more of an enhanced feature on the existing network, or is it truly an entirely different network? If I got an Edge-enabled BB, is there at least a chance that my signal issues improve at home?
