Excellent link. at $2 a call is well worth it.

If you have a landline then there's a chance that your telephone exchange has an automatic wake-up call service. You just dial something like * 55*HHMM# and it calls you back at HH:MM.

Why not use twilio and create an alarm at fraction of the cost? I've been meaning to try them out, maybe i`ll write the script when I get some time.

There are ten times as many issues that can go wrong with twillio compared to your iphone alarm clock.
