Firstly, if this cannot be done in an hour or so, feel free to disregard. If you have a knowledge of the iCal format and OBEX (possibly) to sync to a cell phone, it may be possible, but I'm not sure. On to the idea:
A simple program that will retreive a public iCal URL (such as Google Calendar's) and sync that data with a cell phone via a serial port. No bells and whistles, or editing of the calendar, just that.
If you have the prior knowledge, I hope you're up to the challenge! Thank you!
