On february 10, 2011 the Apple Iphone will be available for Verizon customers. This is huge in the cellular industry because previously the Iphone was only available on the AT&T network. This will change the amount of profit AT&T will recieve. They wont be recieving as many customers from other cellular network companies since they aren't the only company to be offering the Iphone.
Verizon signed the contract with Apple January 11, 2011. This could dramatically increase profit because the Iphone is such a popular phone. It was also a smart descion made by Apple to offer a contract with Verizon. Now Apple has the possiblity of drastically improving sales. This is possible because they arent' limited to just one network company anymore. They have opened another door that was previously closed in the Iphone section of Apple.
