You should search the thread for the OTA update tutorial. Don't use the 2.0.4 image linked somewhere in this thread, some things do not work properly with this image, use the 2.0.1.11 image linked in the first post. Do not update to 2.1 versions. 2.0.5.6 is the last working one and officially released one. You could also use one of my custom kernels and minimecs bluetooth sleep patch for some extra features and battery juice.
