Does anybody know if there is an messenger application for N70 which works?
I've tested several versions of IM+ and Agile messenger and none of them
worked. I have unlimited GPRS traffic but I dislike the Yahoo's wap page for
meesenger, too many Back, Check new message... and so on. My firmware
is 2.0536.0.2/12-09-2006. Any help/answers will be appreciated.

Several... I saw a IM+ working. Also Quick IM, Ultra IM and eMSN.

You could try the Yahoo Go app.

It comes with a full Yahoo messenger

Thanks Dr Tran, you're the man. Finally something which works + it's free.
