This lightweight mobile skin that we have installed, is a free modification that we added to make the forum more readable from a mobile device. It has it's bugs, and I believe they are out of our control or possibly very fiddly to fix. The other options are Tapatalk and ForumRunner which we do support, however these are paid apps for the user.

I'm not aware of any issue like that with Forum Runner. I'll need to have a look when I'm next using my iPod.
