So, all of a sudden, my G1 froze up and I had to take the battery out in order to get it working. Now, it no longer locks when I press the red power button, or when it is left idle. Also, when I press and hold the power button, the only option available is to turn off the power. The "Airplane Mode" and the third option... I think it was Standby... are gone. This is pretty annoying, since I can't lock the phone anymore. Any help would be great. I'm at v1.6 for the firmware. Thanks!
