just a little something I saw on the net. Will try this on my fone coz some idiot played around with it until na lock:

That will still not solve everything but start there

and then go through the bullets below.
Some workarounds to try before reading ahead:
1. try entering null as password. (together with

your google username)
2. try entering your username without

@gmail.com
3. Combine 1 and 2
4. Call yourself from another phone, answer,

without hanging up press the home button, then

menu button, settings, try to disable pattern-lock
5. Call yourself from another phone, answer,

hang-up, directly after hanging up start pressing

your buttons like a madman for <30-60 seconds

ending with your home button (might take a

while to get the timing right). Go into settings

and disable pattern-lock.
6. Try the normal recover password routine

from GMail.com and start over from 1.
7. Perform a factory reset. YOU WILL LOSE

all not-synced DATA (SD card will be left

untouched).
1-6 are possible workarounds, these doesn't

work for everyone but can be worth a try to avoid

factory reset. 6. is what should work but hardly

never does. 7 - The factory reset always work
