I lost my iPhone 4s how can I get it back?

I lost my iPhone yesterday and I'm really worried about it. I don't have a passcode lock on it and last time I had it it had 40-50% battery left so i don't know if it died or not or if someone just has it. I tried the Find My iPhone app but my phone doesn't have any Wi-Fi so it can't connect. And since it can't connect thats how I know its not in my house or it would be connected. I also tried calling it and I left a voicemail with a number to call. But seriously, i'm gonna flip if someone has it and is just looking through it. I have AT&T if that matters. Is there anything I can do!

Keep trying the find my phone, because maybe if someone took it will connect to Wi-Fi. If that fails, keep looking everywhere you were yesterday, and possibly you will find it.

Really just depends on where you lost it, i knew someone who lost their iphone on the bus… If that's the case your not seeing that iphone again. I don't think AT&T can do much but you should still ask, ps. I saw walmart selling iphone 4s for 89 bucks last week, if you don't find it.(sorry i couldn't be more helpful.

How is it only on Wi-Fi? Did you cancel the service? And there's not much that can be done except for find my iphone. Keep trying to use it, because if someone DOES have it and wants to use it, they'll eventually have to connect to Wi-Fi and thats your best time to track them down.
