Hello,I'm currently a Talks user, and like all aspects of it, but am interested in learning about Voiceover and iPhones.My first question, is speech from VoiceOver supported while on an active call? For example, caller id, reading/sending a text, surfing the web, etc? I heard that it was.Secondly, would I have to use a headset to use the phone, or does the screen lock itself while on a call, or would I be pressing things with my cheek, like speaker phone, etc.And thirdly, how accessible are the gps apps? Will they read out street names as you are traveling by car, or walking? Can you plug in a route, and get VoiceOver to read the directions back?Thanks, Shane.
