Here is a useful AppleScript that I use to synchronize my mac with my phone over bluetooth.
Add this to crontab:
30 11,16 * * 1,2,3,4,5 osascript /Library/Application\ Support/iSync/SyncNow.scpt
Here are the contents of SyncNow.scpt :
tell application "Finder"
set iSyncRunning to (number of items in (processes whose name is "iSync") is greater than 0)
tell application "Finder" to set visible of process "iSync" to false
tell application "iSync" to synchronize
tell application "iSync"
repeat while (syncing is true)
if iSyncRunning is not true then
