Last time I used it, it was pretty good. Lacking WPA and the ability to configure IP addresses and a few other odds and ends you would normally expect, but if you need something in a hurry it's absolutely more than good enough.
i have been using joiku since my n82 and i love it..... hate the fact that i cannot remove the JOIKU from this version tho.... was able to do it on the symbian version. anyone know if the .ini file (if there is one) contsains that info? or if its deletable or able to be altered?
