Okay, so i've been recieving at least one e-mail a day on this for the past two weeks. About time I post it here.
When checking Dokuga on your blackberry, you may come to a screen where it tells you that you've been banned.
But blackberry has a roaming IP address and it glitches with Dokuga at times. People will see that they can access a page one minute, get a banned notice the next. Please don't freak out, it's all okay.
Just try and check Dokuga on a computer instead. So far blackberry is the only smartphone with this issue. I haven't seen anybody have this issue with their iPhone or other phone, but yes to Blackberry.
So, either be patient, or don't check with your blackberry please.
