Apple exclusive contract with AT&T is coming to an end soon. The tech industry has wide speculation about Apple’s move once the chains have finally been broken. Some say Verizon is the likely carrier as it is the next largest cell phone provider in the United States. Apple could also squeeze out some of the competitors, like the many Android phones Verizon has done so well with up until this point.
This would increase sales for the iPhone 4 while also putting the hurt on any other smartphone Verizon may have at the moment. Of course, there are other rumors that Apple could turn to Sprint or T-mobile but the odds are less so for T-Mobile as it is the smaller of the top four US carriers and runs on a different frequency that is not compatible with the iPhone 4.
