If you mean setting for example a phone shortcut then select icon and choose system icon...this works fine for me no errors.
No problems with reboots after taking pictures here also none when switching 2g and 3g.
Are you both on clean installs? Before posting bugs it's really best to try and replicate the bug on a clean install with no apps or data restored. Just to be sure. I had issues after using OTA but none after a clean install.
I installed r1 on a completely clean install, then just done ota.
Might try a new clean install to see if it solves some of this problems.
