I used to use SyncMe Wireless but now I have a mac and SyncMe doesnt support the afp file sharing protocol. So I run a ssh server on the phone and use rsync over ssh to sync the folders. This is a different approach. Instead of the phone asking the computer when the files have changed. I run rsync from my computer which connects to the phone and does the update.

To install ssh on the phone install BusyBox and SSHDroid

To install rsync on the phone grab the binary http://adqmisc.googlecode.com/ .. rsync.gz (I put mine in /usr/local/bin)

When running rsync I had to add these options --modify-window=60 --no-perms --no-t
