Yep. Your revision is 2204. Now I think this is the best revision out there in terms of quality control. My reasoning is well, personal experience. Owned 3 N900s (2101, 2104, 2204) and the first two won't OC past 805MHz. I also had to fix my 2104's USB port, and the screen on the 2101 developed dead pixels on the upper right corner. 2204 though, still running like a champ, undervolts and overclocks to the limits, and still rocking a solid USB port.
