Its just rebooted again, this time on wifi, while using the browser.

I've checked the "/proc/bootreason" and it says sw_rst. ThIs makes me think software not hardware.

I have a new sim I'll activate in the morning, but given is was running on wifi at the time I'm thinking it may be something else.

cat /var/lib/dsme/staats/* shows the following

/usr/bin/systemui: 1
/usr/bin/hildon-home: 1
/usr/bin/camera-ui: 4
/usr/bin/systemui: 1
/usr/bin/hildon-home: 1
/usr/bin/camera-ui: 3

Any ideas anyone ?
