Hello all. My name is jimmy. I myself am not visually impaired however I have two blind sister,one of which just purchased an i phone 4 s. Siri works well for opening itunes and allowing her to select stations,and allowing her to text message which she is loving.. I am going to work with her on how to use the voice over function which I think once she learns her way around the phone will work well for her,however I would like to find an app or apps that wil allow her to give voice commands for things such as answering calls announcing caller I D, making facebook posts etc....I have searched google for these apps but the choices seem to be vast and I want the best ones the first try instead of the whole trial and error thing,so I come searching for the advise from the experienced. Any and all info is greatly appreciated. If this works for Kim we are going to get my other sister an I phone. thanks again.
