Hi. Basicly i had put a pattern lock on my phone but somehow its automaticly locked its self and is now asking for s google account password and sign in, but i have tried repetedley to unlock it snd have tryed every pass word and every email. Still tryin to figure out why it has done thiss? Still no luck,could giive me some advice on how to get it back on? The most i can fo with my phone now is recive calls.

I guess you are using a Android phone as it asking for your google password and username. The reason it is asking is because you entered your pattern in wrong 5times.
The one it is wanting is the username and password you used when setting the phone up and setting the marketplace up. If you don't use gmail as your standard account I can see how this would be frustrating and difficult to remember.
Now unfortunately if you can not remember your information then there is only one way to get back on your phone. It is called a hard reset. Now this is a drastic option, as it wipes your phones memory completely so it will be like a brand new phone. No contacts, no apps, no messages everything will be gone.
I can not walk you through a hard reset I am afraid as do not know your phone make or model so I can not help you there. You could google [make][model]android hard reset. And that should come up a tutorial or video.

I hope this helps.
