The very long story made very short: I have four micro SD cards. All have worked fine in other devices. The two 8 GB ones cause my 810 to spontaneously reboot after being on about 90 seconds. Over and over. The 2 GB and the 4 GB, no such problem. I have tried formatting in both my computer and in the phone, no difference.
The long and the ugly: So I got my pristine used 810 two weeks ago. I didn't have a micro SIM, and my SIM punch took forever to get here. In the meantime I used my 8 GB SD labeled "NOKIAmem" fresh from my C7, and familiarized myself with the phone, etc. No problems, never a reboot. At last the punch came, I inserted the now micro-SIM into the phone...........................and it started spontaneously rebooting. I took the SIM out, still rebooting. Since the only thing that had changed was the SIM, I did what I shoulda done and drove to the TM store where they set me up with a new micro SIM. Still rebooting.
Fortunately for me, the seller on eBay had a couple more phones and had no problem exchanging it. I spent several hours with that older phone trying every conceivable combination of SIM, SD cards, formatting, data on, data off, charging or not, etc. Nothing consistent.
Since Nokia hasn't seen fit to allow placing apps and maps on the SD card, I guess I'm OK with 4 GB. But, still..................
