Hello all: need to use my Iphone with my external bluetooth keyboard like a macbook or something. each time i tried doing that, i feel that there is a problem. how can i study the keyboard usage to be easy to navigate etc? i tried the VOice over tutorial, but i did not get what i need exactly, One of my friends was having her Ipad, i tried it with A bluetooth keyboard, and it was amazing, i feel that am inside a mac Environment. so, any tips and tricks will be highly appreciated. or i should purchase an Ipad to do so?
