Apple is looking to add another carrier to help ensure that the iPhone continues its rate of growth. While Verizon would make the most sense with its 93 million subscribers, Kaufman Bros.’s Shaw Wu thinks that Sprint with 48 million and T-Mobile with 34 million could also work out.

“From our understanding, the Verizon negotiations are not finalized with important details still being ironed out, including technology and economics,” writes Wu. “We think it is premature to rule out T-Mobile or Sprint (who also uses CDMA but WiMAX for 4G). In addition, there is the possibility of multiple U.S. carriers being signed.”

Ultimately, it may come down to which carrier is willing to pay Apple the most for the privilege of adding the iPhone.
