Just noticed this ars technica article on a new Apple patent.
"Future iPhones could utilize technology that converts text to voice messages and do so over voice channels instead of GSM. Such a system is described in a recently-published patent filed by Apple called "Multimedia data transfer for a personal communication device," which would essentially turn the mobile devices into walkie talkies for multimedia data. It could also serve to benefit users who are visually impaired by providing vocalized versions of the data being sent."
