How to find classmates on facebook on iPhone?

I have tried through the App and can't find the option at all. I tried going through safari but it always changes to the mobile site, which is the same as the app. Any suggestions on how to get to this option? I tried using the ehow site to do it and that didn't work either. It said there was a drop down arrow next to the search option but I don't see it.

My Iphone 4 won't turn on.what can I do?

Randomly when I went to check my phone it wouldn't turn on… The screen is just black… I've tried charging it with different chargers and even tried plugging it into my computer… I've called Apple but it's $35 to get help. A lot of reviews are telling me to hold my lock and home screen down for 10-30 seconds but my lock screen is jammed so that doesn't help… Please someone tell me there's SOMETHING I can do? (not including buying a new phone)
