So you have your shiney new iPhone. And it works great. Now What?
Sit back and watch the carriers fall to pieces. Now that Apple has their foot in the door there will be no stopping them. The big carriers just don't get it, they don't understand that what consumers want is ease of use, and a consistent experience with their phone. They want that Star-Trek moment and it better work every time. If there is a problem with it, they want friendly and helpful people to fix the problem without over charging them. None of the carriers have good customer service reputations, they gouge their customers at every turn and dare them to risk terminating a long term contract to go with a rival where the experience will be just as bad.
Along with every "iPhone is great" post going up on blogs around the country, there are posts going up about how bad the AT&T experience was. As Apple gains power in this market they will continue to do things right, while the carriers continue to do them wrong. Overtime the carriers will become less important while the new little portable computers that Apple, and hopefully other companies, make will become whats important. The phone buisness will be just another computer buisness. The carriers like AT&T will become just another internet provider wondering where all the cash went.
It won't happen overnight, and it won't be without a fight, but I for one can't wait for it.
