[Trainer-talk] iPhone 4 information

[Sarah]

hello. I upgraded to the iPhone 4 a few days ago. I appreciate the fact that the phone is accessible right out of the box, but I am having some difficulty  with the device. One problem is opening, deleting, and composing text messages. I guess I'm just not familiar with using gestures to operate the phone as opposed to buttons and software such as MobileSpeak. I also do not know how to enter numbers on the keypad such as when calling a company that requires entering numbers to speak to a customer service representative. I guess I'm just having misgivings about the phone purchase. is this device accessible enough for a totally blind person, or should I stick with my old phone that uses mobile speak? If I keep the phone, would I benefit from a wireless keyboard?  Thank you.
