Thanks for the suggestions guys, but no luck yet. I tried BOP5's method first but it just didn't seem to be working, so I thought I'd give TLS's a go. It's a nice plugin you've linked to but I can't get it to work. I downloaded a huge list of Opera Mini UA strings, put them in the mod and turned it all on but nothing's changed.
It doesn't seem to be registering that I'm accessing the forum on my phone with Opera Mini as there's no output to the log file. I know Opera Mini was designed to be a royal PITA through and through but I can't make sense of this...
Any ideas? Cheers!
