Its simple to get the phone unlocked, call your phone from another phone, during the conversation press home. Now go into settings create a new gmail account with a password that you know. ( if you dont have one make one). Now hang up and when you go back to that lock screen type in the new account you set up.
I didnt read the whole thread to see if youve already so sorry if this information is useless now
I dont understand why but I posted this already step by step in the other thread he started..
He has 2 threads going for the same topic.
Here it is once and for all.
anyway heres the fix credit to bostondroid
1) create a new gmail account on the computer.
2) call your cell phone with a different phone.
3) answer your cell phone then hit the back button and it will take you to the home
screen.
4) turn on wifi so it can do data and voice at the same time (remember that the phone
is still connected)
5) go to Settings -> Location & Security and disable lock pattern (you'll need to
enter to correct pattern previously set)
6) go to Settings -> Accounts & Sync and click "Add Account" and add your newly
created Gmail account.
7) hang up the phone.
8) turn the phone back on, at the lockout screen, enter your new Gmail account info
and it should let you back in
9) once the phone is unlocked, you can go in setting and remove the newly added Gmail
account and keep the old one.
If this doesnt work remember to use the "search" feature I found the answer to this in less than a minute.
