Back in the old days I used to sync a nokia 9500 and a Sony Ericsson P900 with outlook over a cable. I was pretty confident in that it worked and all appointments and events including repeats where duplicated correctly on each phone. It wasn't until my permanent move to linux that I needed to find a cross platform solution that didn't rely on a PC. I had always used exchange and had found the S60 and windows mobile exchange syncing to be fine but there could be issues with duplicates or missing entries. I would then spend valuable time tweaking them until they appeared on both devices correctly. Recently I have expanded the syncing to an android based HTC Hero, Maemo n900 and WEBOS Palm Pre. I have always sought to have a devicer with exchange syncing. Today on looking in my n900 calendar a recurring birthday hadn't synced. I tried a full resync then extended my search to my other devices to see which one it appeared on. My E63 and Palm Pre synced the event fine bit bot
