[Samsung Galaxy Spica] Pattern lock

Issue

I have a Samsung Galaxy Spica, and unfortunately I wrongly entered the unlock pattern (5 times) and now it is locked. 

It's asking me to enter my google account. I entered my address and code several times but it did not work. 

Solution

• Turn off your phone and then turn it on - you must enter your PIN code
• After entering the PIN code , you'll be ask to enter the Google code (Don't do it)
• Ask someone to call you

Even if the phone is locked you will be able to answer the call (green key)

• the press the return key.
• Go to Menu > Settings > Security and then you can uncheck security pattern required
• You will get pattern you had selected to block your phone earlier
• Re-enable this feature if necessaty
• At that moment, you can hang up your phone, it shall be unlock
