Hi everyone. Came up with a little script that allows one to update his/her journal through a WAP browser on a mobile phone. It's called wapLJ and you can see it in action (from a WAP browser) at [ http://sumeet.info/wapLJ/ ].
It's a WML page that accepts values and posts your entry through the XML-RPC interface that LiveJournal servers provide.
You can download the source [ZIP file, 12 KB], host it on your servers and run your own install of wapLJ ! :D
