[th0mas] has put together a concise how-to on forwarding Atom or RSS to you cellphone. In his example he grabs an Atom feed from his Gmail account then parses it to find the new messages.
The new message list is compared to a file so that duplicate messages aren’t sent. All new messages are then sent to the phone’s email address. th0mas has provided enough information so that this script could be easily expanded. It looks like a decent introduction to PERL as well, so even if you aren’t looking to send stuff to your cellphone it might still be worth a look.
