Sign all of the petitions you want, but the merger will go through because of the $ that at&t is pumping into the regulators. It's just reality.
T-Mobile customers: Don't like how things are heading? Vote with your wallet ($), just move your service/phone number to Sprint. They're offering $125 port-in credit right now (until 4/16/11). If you have plenty of $$$ and don't mind paying more, V might even be a option for you.
