It's meaningless. Gingerbread + gingerbread_update1 include all files that is really needed.

libbridge.so exists in 0.0.9, but removed from Gingerbread update intentionally, because DSP is not working yet. What happens when you install Gingerbread on fresh 0.0.9? Codecs will attempt to use DspBridge and fail after few retries (check logcat).

FakeGPS - i don't know why do you think it's working... try to locate yourself in GMaps... if you find yourself somewhere... in Russia... then it's really working
