Will my text messages still be on my iPhone?

Thursday, the power button on my iPhone 4S completely broke. It was not dropped or anything, just broke randomly. I ended up using the assistant touch thing, and going to device and tapping lock screen. I was playing around with assistant touch and accidentally hit 3 finger gestures. I couldn't even touch my phone. I took it to AT&T Saturday and they told me it wou, d have to be sent to apple, and that I will get a brand new iPhone Wednesday. I know I probably have quite a few text messages, and I'm just wondering if they will be there when I get it back? I'm pretty sure it will be just like having a brand new iPhone, no numbers or anything. I know I cold use icloud, but I never use Wi-Fi so I don't know if it backs it up and it wasn't backed up to iTunes. So will I be able to see my text messages?

They should be if you have the same sim? Did you take the sim out? If you did all your texts should be still on the sim but your sim should still be in the phone. Let your friends know over a social networking site
