g-i don't know about "opera-mobile" but i use "opera-mini" on my nokia 6131 and it is free to d/l and the only uasage charges are those associated with my cell phone data plan. i just checked here (http://www.opera.com/products/mobile/) and it looks like opera-mobile is $$ but if your phone can use opera-mini, it's not bad for a quick on-line session. n.b. you do have to set up the "access point" on your phone for opera-mini to connect but i found the settings in the "forum" section on the opera mini home page.
