Mine's been totally freaky last few weeks. Random reboots galore (no led flashing, just blacl screen then jolla logo and if lucky once (i think i found new reason for reboots: bright sunlight, not enough to be sure but 4 times already going onto balcony from inside room caused a reboot loop, either plugging in or battery out helps), if unlucky bootloop). I took my n900 to take picture of iOs+Jolla (greeks with their screwy alphabet spell it Ios, whatevs), one interesting thing: make sure jolla sees the wepsecured network you try to access, half of them are unavailable. Other than that it's been great, but good poiny, might wait with the update until back with pc on hand
