After running smsimporter, I updated the el.db with sqlite3 with "update events set storage_time = start_time" and the order in the conversation view didn't change (even after a reboot). I'm thinking it uses the ID numbers for ordering, so I suppose I will try to renumber the messages at some point. (..I hope there are no references to the ID-number, it didn't look that way..) However, I will likely try it only once I get to import very many more messages from my old trusty 9300i - once I get its display fixed..
