If you want to do e-mail syncing on most mobile devices, NuevaSync[1] provides an ActiveSync interface for any IMAP-capable e-mail account. I'm using them to do calendar sync to a device that doesn't do iCal and the service has performed quite well. Nueva even offers device wipe as an included feature.
