I lost my iphone, and I have no clue what to do?

Obviously, being the teenager I'm, I got a little too drunk and lost my iphone 5c last night.

I Can't FIND IT ANYWHERE.

My location services are off, and it is dead. Is there any way an Apple person can turn those location services on and track my cell phone? I'm not sure if someone stole it or if its just gone, but I'm out of options.

Is there an easy way to read messages from a really long time ago?

I have this conversation with someone and I haven't deleted any messages. I want to read messages from over a year ago but don't want to keep clicking on the button to go back farther because that will take a very long time. I have an iPhone 4s. Is there an easier way to do this?

IPhones service being off and Wi-Fi/imessages?

1. My boyfriend is in Japan at the moment
2. He told me his phone would be off for about 2 weeks but he would be able to get and reply to messages only when connected to wi-fi
3. My imessages are saying delivered yet I'm not getting anything back from him at all

Is he lying or is something going on so that he's still not receiving messages? I was thinking that since he is overseas its some other issue he may have with the carrier but I thought imessage would work regardless?

Is it worth getting an iPhone 4S 8GB?

I was going to get an iPhone 4S 8GB, but is 8GB enough? I want a phone with a good camera, so I'd be taking a lot of photos as well as have a lot of music on there. I wouldn't have many apps because 1. I'm not an app sort of person. 2. I have an iPad that has all of my favourite apps on it.

Would 8GB be enough?
