Verizon is threading a very fine line these days with this latest push on Bing.  One of the biggest draw for the iPhone is customization.  If Verizon doesn't get that and force their clients to use their phones a certain way, their days are numbered.  If they are smart, they'll bring back the other search providers.  If they pull another stunt like this, I'd rather pay the early termination fee and go with AT&T.  I frankly don't care about coverage in middle America and it won't be long before AT&T catches up anyway.  Verizon, get a clue.
