[kosalnarin]

Dear Sir

My Phone is Sony Ericsson Arc S. I was used the pattern, It's can unlock the screen. Next I used the PIN, I't's can unlock the screen. But when I used the password, I cannot unlock the screen. Beacuse it's dont have keyboard for press the password. So, what can I do? How can I unlock the screen from the password security?

please help me.. 

Thanks !

I'm a bit confused, is it that you can NOT unlock it because you forgot your password?
