Yesterday when I fiddling with my Wonder, I found a way how to bypass Android's lock verification system. Unfortunately, I was sleepy and I only can remember some parts of it. Notice how I use the word 'verification' and not 'screen' as this does NOT disable the screen. The screen will still appear however it will accept any pattern. This 'hack' is persistent and does not reset after a reboot, when I attempt to change the locking method, Android does not ask for a pin or pattern. This might work with other phones but I have not confirmed that. To perform this, switch of your phone and power it on again normally. Right after the boot animation, the soft keys will light up. Immediately, press and hold the menu key. When the lock screen appears, quickly let go of it and press and hold it again for another few seconds. Notice how the status bar dims, if that happens you have performed the bypass successfully. Android should now accept any pattern whatsoever. I have not been successful in recreating this 'accident'. Let me know if this works for you. And if your an experienced user and know what is causing this to happen, please enlighten me.
