I noticed some threads about lost or stolen Fairphones
I wonder if we should try to have a community wiki page on the lost and stolen phones, with IMEIs and $discoursehandle only - so if a lost or stolen phone pops up somewhere (e.g., on eBay), the previous owner could be notified via private message. I’m not sure about it, because such a notification is of limited practical use only, and might just lead to further annoyances, i.e. not being able to get the phone back, or realising that you spent money on a phone which belongs to someone else.
I don’t think a seller of a stolen phone will voluntarily tell you the IMEI, but we could ask everybody on the forum who got his phone second hand to check the list of IMEIs of stolen phones. Then the buyer can report the seller to the authorities.
I say let’s try, worst case we have an idle wiki post.
IMEI1 is on a sticker on the back of the white “Open it, it’s yours” package.
IMEI2 can be calculated from IMEI1: Remove the last digit, increase the resulting number by 1, calculate the new last digit and append it. You can see on Wikipedia how the last digit is calculated, try that first with IMEI1 before calculating IMEI2’s last digit.
