yes, this is the one.

I tried it a couple of months back... received the link, however, I can't download the JAR file, system prompted me that my mobile phone model - SE C905, isn't compatible.

If it works for SE K850i, I'm pretty sure it works too for SE C905, because they didn't put SE C905 in the list, hence, the site didn't allow me to download, and makan the duit.

If I have the JAR, I'm pretty sure I can install the mobile authenticator.

So unless your phone model is listed, other wise, don't download.

>_<

btw... there's already an existing thread on this.
