You where right, I took out the 3.3v and works fine but I need the pullup resistors, if I take them away stops communicating.
Ok, so it's working, but why the values are so erratic?
the temperature reading looks kind of stable, but I leave the board steady on the table and the values change dramatically.

I really can't see a relation between them.
If I move the board I can't either see a pattern between the movement and the numbers.
Anyway Krodal, You helped a lot! Thanks!!!!! in that page it says that the I2C address is 0x69. Anyway, I've learned a lot finding it out by myself.
