Plus if Verizon is really getting the iPhone there will be more competition with pricing.
I fell out of my chair LAUGHING at this statement.

The idea of "competition" between Verizon and AT&T is a complete myth. Both companies watch each other closely and as soon as one company makes a move regarding a price increase or a restriction on a certain feature, the other follows suit. A couple years ago Verizon redefined "unlimited" laptop data to mean 5GB per month max. Shortly thereafter, AT&T and Sprint did the same thing. Prices didn't go down, yet we all got less for it. Now the plans are changing for smartphones in a similar fashion.
Unfortunately there is not enough competition. Instead you have two industry superpowers,
carving up smaller regional carriers amongst each other for their mutual benefit, and matching each other's pricing moves tit for tat, but in ways unfavorable to customers. And unfortunately, Sprint screwed themselves over with the Nextel merger and alienated so many of their customers that they're no longer relevant and have no influence now.
Meanwhile T-Mobile prefers to only invest the bare minimum in their network so that they have a cheap roaming option in major cities for their European clients, and if they can attract a few bargain hunters in the US who don't mind horrible coverage outside of metro areas, so much the better.
If ever Verizon gets the iPhone - and I still doubt it will happen anytime soon -
none of this will change. The best we can hope for is they'll match the current pricing structure at AT&T, if not
raise the prices to avoid anyone overtaxing their precious network and giving them the same issues AT&T has had. And you can bet if Verizon makes owning an iPhone more expensive, AT&T's management will feel dumb about that and raise their rates or restrict their features further, too.
The sad thing is, it's no better in other countries, some of which have
never had unlimited data for iPhones.
