My g1 got locked because of to many patern atempts what should i do ?

You can do a hard reset and that will allow you to get into the phone but it will wipe everything out of the phone:

Turn the G1 off. If it’s frozen on, take the battery out and put it back in the unit.2. Hold the Home and Power keys down at same time for about 25 seconds. You will see a yellow triangle screen with exclamation point in the middle.
Now to wipe the device clean:
3. Press Alt+L.
4. Press Alt+W for a factory reset.
5. Press the Home and Back keys again for about 25 seconds.
The device should then reset again and the hard reset is complete.
