Look, I'm absolustely fed up with micropayment cripple ware. a simple app like should be free. period. i'm not going to give you $6 just because you saved me 5 minutes to write an apple script and create a cron job.

and for those who want to pay for this, here's how to sync your phone once a night for free.

open apple's script editor, and make an apple script with this:

tell application "iSync"
activate
synchronize
repeat while syncing
end repeat
quit
end tell

save this as a file (sync.scpt) wherever you like

open terminal.app (/Applications/Utilities/Terminal.app) and run the command 'crontab -e' to edit your cron file, which lets you set actions with dates.

add this line to the file:
0 3 * * * osascript ~/Documents/syncscript.scpt

Replacing ~/Documents/syncscript.scpt with wherever you put your script. the 3 means 3am. you can change that to any 0-23 hour you like. the 0 is the minutes. this can be set to 0-59. the last *s just mean every day, month, and year (in other words daily)

save and exit, then you're done.
