Apple has released detailed support information explaining the differences between iPhone calling features on the AT&T and Verizon networks. Because AT&T Mobility uses GSM technology and Verizon Wireless has a CDMA network, each iPhone 4 has different calling capabilities. Recently it was revealed that Verizon's network suffers from conference calling limitations, but there are other differences as well. The table below was released by Apple to illustrate the details.
With all of the anti-iPhone advertising coming out of Verizon lately you'd think the company had no interest at all in dealing with Apple. Apparently this is not the case, considering the words of Verizon CEO Ivan Seidenberg during a third quarter earnings conference call.
Seidenberg explained that the decision to launch an iPhone on Verizon's network is "exclusively in Apple's court. Obviously we would be interested if they thought it would make sense for them to have us as a partner."
Look out Verizon fans, the iPhone may be coming sooner than you think. AT&T must be nervous considering reports that the other wireless giant, Verizon Wireless, is currently in high-level talks with Apple about the iPhone. Vodafone, the co-owner of Verizon Wireless, already offers the iPhone in European markets.
It's possible that Apple is considering a CDMA version of the iPhone after all. Observers are predicting that if Verizon and Apple can strike a deal, the iPhone will hit Verizon shelves as early as 2010. AT&T has been trying to extent its exclusive arrangement with Apple beyond its expiration sometime next year into 2011.
