How to unlock my iPhone 4S without passcode?

I forgot the the password and need to unlock it preferably with everything on and without a computer.
I'm on Vodafone is there anyone I can ring or can I ring the apple store?

Ya you can on Google ther are many solutions given you can pick code from there.

If you go into town, there should be many places where they can unlock your phone keeping all of your things in it. If worst comes to worse and you can't find anywhere in town to unlock your phone, then connect your iPhone to iTunes and click restore. Sometimes this gets rid of all of your things but the last few times that I've done it, it hasn't (I forget my password a lot!)
Hope this helps!
