So, unless you are an AT&T "fanboi" so to speak (I get really sick of seeing that word thrown around here though whenever some one wants to debunk some one else), overall Verizon getting an iphone is good for us all, even if you prefer AT&T. Goods for Verizon users: 1. The fact that they get an iphone of course Good for AT&T users: 1. More iphones out so that means more developers/companies tempted to make apps for it. 2. Less stress on the network Good for both: 1. Both companies will have competition and will have to stay competitive. Means they will at least keep each other in check. And you may see them offering more perks to encourage you to go to them instead. Bad for Verizon users: 1. Well, for the non iPhone users the network gets stressed more. Depending on how well Verizon prepared, they may find Verizon starts having issues. But Verizon does have the advantage of hindsight so I'd predict this won't have too big of an impact (or at least not as big as it did on AT&T when it got the iPhone). 2. If AT&T goes under cause of this less competition for Verizon. This would have more affect on everyone than the added competition of Verizon cause this is less competition for all phones, not just iPhone. AT&T existing is good for other carriers' customers (though not for the other carriers' ). Bad for AT&T users: 1. The people you call the most might change to Verizon so you won't get free mobile to mobile with them. This can be softened by the fact they would be moving to get iPhones so you can reduce the minutes used by face talking them when they are on wi-fi (if you really need the minutes and don't want to go up a voice plan). 2. If AT&T is that horrible that enough people lose they go out of business or get bought out (the latter could be good or bad depending on policies of company buying out). But that would be more the fault of AT&T failing to be competitive enough.
