Finally...?
Well, this can hardly be worse than the last FCC Chairman, who seemed to think that we'd benefit from having a 100% telecoms monopoly under AT&T.
@ Jim Metz:
Just ignore or forward the yahoo email to an address you'd like to use, and don't let them mess with your browser. I'm sure they haven't blocked Google or Bing or whatever you'd rather use than Yahoo. I have a feeling that blocking Google would lose them customers and earn them a lawsuit asap, while blocking Bing would probably just get them a lawsuit.
@ KingZongo:
For your plan to work, it'd require all mobile service providers to use compatible wireless technologies. There's no way to take a phone that will work with AT&T (GSM) and take it to Verizon or Sprint (CDMA.) Since AT&T and Verizon are the only two providers that really count, size-wise, and they are incompatible, it doesn't matter a whole lot whether they keep you on their network, since there's nowhere else to go.
The GSM vs CDMA mess is really the root of this country's wireless problems, and it's probably not going to change in the near future.
