Then I have to just sit and wait.

Or is there any magic that I can store to the eeprom to keep it active?

So unfortunately you have to wait for next update before you can 
unable 3.3V pin from user space. But that should happen 'soon'...

Anchors aweigh!

Just hooked up scope to I2C bus on pogo pins, and there is life!

Can someone point me in correct direction to enable 3.3V pin?

3.3V seems to be active just for a while when I press the cover 
detector switch and after eeprom in address 0x50 is tested 3.3V is gone.
