So my iPhone completely crashed on me last week, it was the iPhone 4 I purchased last year in May. The ios came out last year in the fall. So I went and got my screwed up iPhone replaced and they gave me a new iPhone 4. I have Verizon by the way. So I got my new iPhone and it said upgrade in the settings area. So I upgraded this ios 5.1 now I want to know how do you turn on the voice command. I tried to tell my phone to search this or that, but nothing worked.
