Iphone 4 stays lit and won't turn off, how can i fix this?

My phone's screen is dark but also lit up at the same time (there's no logo, no picture ect.) it won't force shut down, and my computer doesn't even know its plugged in when i hook up the usb chord. In other words, my iphone is not responding to anything i do.
History Behind the Phone: i tried to reset the phone to factory settings because it was jailbroken and i was trying to take it off, i couldn't restore it from my computer because the internet was down and it wouldn't let me. So i thought i would go into iphone settings and erase all content, simple enough, right? Well evidently my iphone got mad at me and isn't responding to anything… Please Help!

Why to do about my relationship?

My boyfriend and I have been together for 2 yrs. He lives an hr away and we see each thee on weekends. Lately, during our Christmas break he would go a day without texting me or take forever to respond an that's something he never does. We had a major rough patch during the break but cleared it up. But break is over now and today he didn't text or call and I did. He didn't answer any texts or calls. He finally emailed me back saying he was in the library and doesn't have his phone. But the message said sent from my iPhone. They have Mac in the library. I don't know what's going on. I feel like we have talked about this over and over. Is he cheating? Am I doing something?

Why did I get a text message from an Unknown number?

So I have an iPhone 4 and I got a text message from an Unknown Number. Not a number that I don't know, it literally said "Unknown" where the number was supposed to be. There was no text in the message, and I responded with, "Hi, who's this?" and I got one of those error messages in return.

What does this mean? How do you even send a text message from a blocked number?
