Where should I pre-order the iPhone 5s?

Okay I want to get the iPhone 5s as soon as possible and I did some research and a majority of the websites were saying to pre order it if you want as soon as possible.

Can I still use my old iPhone 3 after I've switched phones? I?

I have an iPhone 3 which I have service with AT&T and had a data, calling and texting plan. I just upgraded to a different phone and it will be delivered shortly. My daughter has a lot of apps on my iPhone and I was wondering can she still use these apps after I have switched to my new phone? Can I still use iMessage? Can I still use safari? Obviously, the phone will no longer have a data plan and I don't want to buy one just for my 3 year old although I will if I have to. So my question is can the iPhone still work (besides making calls) without my being charged? Can I just use the Wi-Fi?
