It looks like we are getting close to the official Android 2.3 Gingerbread firmware release. The PTCRB has just certified a new firmware that judging by the number (3.0.1.G.0.70) is the first Gingerbread software to be certified for the X10.
Don’t everyone get your hopes up though. It will probably take a few weeks for the firmware to hit SEUS (if this is indeed the release candidate, other revisions may be on their way). However, what it does mean is that hopefully the early August release date will be hit.
