    First thing: this forum is used by software developers, and is not for "end user" support. For help using your phone, you should try Nokia Support. For help installing or using Opera Mini, you should go to the Opera Mini Help site.

    Beyond that, I suggest you go to the Opera Mini site and make sure you are downloading the correct version. If you are offered a choice of signed or unsigned versions, choose "unsigned".
