Analyst: Verizon and Apple still "ironing out" details of the pair's iPhone dealThis article contains unofficial information.
For the moment, it would appear that both parties are thinking about using SVDO before switching over to LTE. SVDO is a technology that allows for simultaneous voice and data. Verizon's pipelines currently have different voice and data delivery methods, which could limit the use of certain iPhone apps on Verizon. The carrier is said to working on Voice over Revision A (VoRA) which would merge the delivery of voice and data over Verizon's EV-DO network.
Wu also notes that it would be "premature" to rule out T-Mobile or Sprint as possible recipients of the iPhone. Together, the two carriers serve 82 million customers, many of whom would no doubt love to see Apple's touchscreen device on their current network. Thanks to the strong momentum that Android phones have had in the U.S. over the last 10 months, Apple needs to let the iPhone become available on other carriers in order to sustain the strong sales growth that the device has had this year, thanks to its first redesign.
