Why won't my iPhone screen rotate sideways when I rotate my iPhone?

I know this is the wrong section but you guys are awake and this is serious.

Ok so I asked one of my friends about it and he said that the screen lock might be on. So I a checked information ok the screen lock and found out what it was and everything and turns out my screen lock isn't on. If it was on that twisted arrow thing was suppose to show at the top right hand corner of my phone.

I DOUBLE TAPPED THE HOME SCREEN BUTTON AND THEN FLICKED TO THE RIGHT AND KEPT LOCKING AND UNLOCKING THE SCREEN AD IT STILL DIDN'T WORK.

So since it isn't the screen lock can any one give me any advice on how to fix this problem. Oh yeah and one more thing, I dropped my iPhone so I think that could be it but my iPhone is working fine it's just that one problem.

Btw there are some games where you can only play sideways and it works for those games but that's because in those games you can ONLY play sideways.

I have a strange feeling it has to do with me dropping my phone but everything else is working fine.

So I would really appreciate it if you could help me.

Before you answer my question re-read the 3rd paragraph.

Added (1). @ Dreamstuff - Only tilt based games work but that's it. Even YouTube videos won't tilt.

Jailbroken iPhone Update Errors?

So I jailbroke my iPhone months back and I've been meaning to un-jailbreak it for awhile now but somehow I just have never got around to it. Anyways, I forgot about the fact that it was jailbroken (silly me) and tried to update the software. Now, I'm stuck with a phone that will only beg me to connect back to iTunes. Every time I do this, iTunes instructs me to restore and update it. I tried this once for the hell of it but nothing has changed. How do I get my phone working again? I don't care if it's completely wiped when I turn it back on, I just need it available.

Why won't Cydia download/install anything on my iPhone?

I just jailbroke my iPhone 4 w/iOS 6.1 today. But when I went to install the winterboard or any other program it won't work. Messages like "Internal Server Error", or "Timed Out" or "Source Error" comes up in red letters. I've tried on 3G and my Wi-Fi connection and it still won't install anything. Any thoughts people? Are the boys at Cydia or the other sources still working on iOS 6.1 stuff?
