Pop-jisyo is indeed incredibly useful... Less compatible but slightly better (by my rather subjective standards) is Rikai: http://www.rikai.com And btw, since we are on the topic of translations, time for a bit of shameless self-promotion: the quick n dirty cgi hack I wrote to bridge keitai mail with Jim Breen's WWWJDIC ( http://ryouko.imsb.nrc.ca/~j breen/wwwjdic.html ) is now pretty much officially out of alpha phase and damn convenient if you tend to exchange keitai mails with people who have little regards for your kanji-reading limitations: http://www.unknowngenius.com /blog/archives/000213.html it will probably soon move over to Jim's server (as soon as I have time to tidy up the code some more and send it to him).
it seems the evil line-breaker script doesn't like long URLs (and I completely forgot to put hrefs tags): be careful to stick back all the pieces before use of the above links...
