Thanks for your report. We didn't experience this instability with this release, I am a little surprised. Can you let me know what is the rev. of your board (B1 or C1) and the amount of RAM you have (256 or 512) ?
Bluetooth still needs to be fixed, but if you have a 512MB unit, it should work when starting Android from AIOS (but not when booting directly).
