I will help you with ringtones tommorrow as it's a little tricky, however , regarding SSH:
Very basically:
If an iPhone is SSH enabled, Using a program such as WinSCP or Putty for windows, you can log into your iPhone and view its hard disk's contents - transfer files, photos, get photos off the phone etc all by using your wireless connection in your home.
This is cool because:
a) No wires are necessary
b) The iPhone does not support disk mode without installing a 3rd party app
If you dont have wireless in your home its pretty much useless to you.
