Control Your TiVo From Your iPhone With TiVoRemote
A user by the name of Duckfin at the TiVo Community Forum has created a native application that turns your iPhone into a TiVo remote. The app, named TiVoRemote, utilizes the TiVo’s Telnet control feature to give you complete control of your TiVo right from your iPhone.
The app is free and easy to install. Just add
http://tivoremote.googlecode.com/svn/www/repo.xml as a source to Installer.app, and locate TiVoRemote in the “Toys” category.
