The Motorola Droid 2 Global should be receiving an OTA update roll out as you read this. This update brings some bug fixes: Out of Memory errors, camera not saving settings after power down, random power-ups and reboots, and a Google Security Patch amongst other things. If you want to manually check for the update go to Settings–> About Phone–> System Update. Keep something in mind though... this update breaks root and causes some other issues for folks who are rooted. It even patches the vulnerability to be able to gain root access.
For stock users, this is a valuable update, but for our tinkerers, you may need to do some more digging in the forums on how to get the benefits of this update without messing things up for your current setup.
