Now 1.4 hf1 come out liao.

Hotfix 1 [24 September 2011]: Fixed wifi tethering (reverted to v5 supplicant - should not reduce wireless quality as we are still using the newer WEXT driver); fixed stock FM radio; improved FM radio volume code (thanks to OuNao); improved FM audio quality (reduced hiss sound).
