I don't know if it's just mine, but I am unable to post to forums using my blackberry. I can review postings, and click on the "reply" button, but the "post" and "preview" buttons are non-responsive.
If anyone else is able to post using their Blackberry, I would love to know your settings. I believe that I was able to at one time, but I can't figure out how to make it work anymore.
Sometimes, BB comes with different browsers...try using different ones. You should be able to change the Java setting in options. What model are you using and which version of the BB operating system?
I can was able to post with my Blackberry Curve without any special settings - just using the Opera browser. Unfortunately my Blackberry is having a nervous breakdown and decided it needs to jump in and out of different programs, mute phone calls half way through, and just plain turn into an evil device. Thank goodness it is still under warranty and the new one arrives on Monday.
