Ok everyone, This is what you are going to do if it did not work for you (and don't forget to backup your stuff because it will erase it):
1) Flash 2.0.6 FW
2) Flash SHIQ
I have tried that a few times and it works great.
For the Wifi, If you mean the notification bar icon, it does not show the real strenght of the network. Check it under the Wifi App to see if it is the same.
Next, I will work on improving battery life and get all the sensors to work correctly.
