I can't find Siri on my IPhone 4S

I've even done the
Settings>General>Restrictions> siri on thing and the option for her wasn't even there. I have AT&T so it should support it.

Hold the button down and she will pop up

What service you have does not matter, AT&T Verizion etc.

On my iPhone 4S, I can go to Settings>>General>>Siri>> then turn her On or Off and change the settings.

If that does not work, then maybe you have an older version of iOS and you need to update it. I have version 5.1.1.

However, I would not particularly recommend that you update past 5 because there are a lot of problems with 6, and some basic features are eliminated like the YouTube app.

Try Settings>General>Siri and then see if it is on and/ or there. If it isn't I would contact Apple right away at 1-800-my- Apple

Just hold the button and keep your phone near, than ask what you want.

You have an iphone… There's your mistake
