You will NEED to master reset your device and add your own Gmail at this point!

A Hard Reset restores the original factory settings and will erase all downloaded content, including ringtones, contacts stored in the handset memory, etc. It does not erase data stored on the SIM card or memory card (if available). Back up all necessary data on the device memory before proceeding.

Menu Path Method:

From the Home screen, press the Menu key.
Touch Settings.
Touch and slide the menu upward.
Touch SD card & phone storage.
Touch Factory data reset.
Touch Reset phone.
Touch Erase everything.
The device will dump all of the data and reload.

Key Stroke Method

Power the device OFF.
Note: If the device is unresponsive and does not turn off, remove the battery and then re-insert it.
Press and hold the Home key and the red End key for 30 seconds. Do not release the keys if the Startup screen appears.
When the screen displays a warning sign, release the keys.
Press the Home key and the Power key again.
When the Android system recovery utility appears, use the trackball to scroll to and select Wipe data/factory reset.
When the reset is complete, select reboot system now
