IPhone help? Anyone know anything about iPhone

I have an iPhone 3gs that I have had for about 4 years or so. About a year and a half ago someone went and changed my passcode on the phone and ended up locking my phone completely, it says that I can try to unlock the phone in like 2 billion hours. I have so many things on the phone, and really would like to get into it. The phone does not have the hold button on top, and I tried to officially reset the phone before and it hasn't worked yet. When I go onto iTunes and try to restore the phone, it says that I have to unlock the phone. So can someone or everyone please help me figure this out. Or give me a websight or something. In detail.

How to stop an iOS update on iPhone 5?

I started the latest ios update on my iPhone but then it came up with a screen saying 'connect to iTunes', and no matter what I try it's not leaving. I tried connecting it to a laptop but it said to restore my iPhone so I just stopped and ejected it. I can't use it now, and even when I try clicking the button or holding down onto the main button and power button at the same time it doesn't make the screen disappear. How can I get rid of it? Should I go to an Apple store?

How to get a factory unlocked iPhone 3GS out of recovery (connect to itunes) mode?

Once the iPhone 3GS is in DFU mode and plugged into iTunes, the restore and update process begins. The restores process are as followed:

Extracting software > Preparing iPhone for restore (blank screen) > Preparing iPhone software for restore > Restoring iPhone software > Verifying iPhone restore > Restoring iPhone firmware > The iPhone can't be restored. An unknown error occurred (1).

I clicked on the more information tab and was taken to a website with some troubleshooting. I did what they suggested (based on the error #) and still no luck. I've tried to restore and update about 10 times now but the same message keeps coming up at the end. What should I do now?

P.S: I have the latest version of iTunes (11), my windows is up to date etc…
