Can't comment from Opera Mini on a Blackberry.
I've tried a couple of times to post comments to the blue from two different models of Blackberry (8700 and 8900). Previously was running an older version of Opera Mini (can't recall which) on an old Blackberry 8700, and when I'd try to post a comment to the blue, it would preview just fine, but when I hit the post button it would load the preview page again. Repeated hitting of the post button just continues to preview. Currently running Opera Mini 4.2.14912 on my new 8900, tried to comment in the Dreamcast thread this morning while waiting at the doctor's office, and got the same problem.
I haven't tried yet posting to other subsites, and of course I don't want to make an FPP just to test if that functions properly in OM. Anyone else seen this?
