The iSync Palm Conduit has no provision for the synchronization of memos. You can place the standard Palm Memos Conduit -
not the ealier, now outdated Memo conduit - back into your active Conduits folder in order to synchronize your memos once again with the Palm Desktop.
Alternatively, you can purchase, download and install The Missing Sync from Mark/Space. This package includes the Mark/Space Memo Conduit and a matching Mac OS X application called mark/Space MemoPad, which precisely mimics your Palm-based Memo Pad application. It also kicks the #$%^ out of iSync, from my perspective, offering configurable and reliable synchronization of contacts, calendars, task or to do data, memo, AvantGo content and lots of other features.
