To use the mobile version of TwitKu, simply enter http://m.TwitKu.com or http://TwitKu.com/m in your mobile browser. You'll be able to monitor Twitter and Jaiku feeds on one page and post to both with one entry just like it's big brother.

Note that you may want to get your Jaiku API key on a PC at http://api.jaiku.com/key and write it down because many mobile browsers can't handle that page properly.
