Actually.
vBulletin 4.0 was launched over a year ago... The functionality of the forum software wasn't hurried, but it's completely different, and really it is much improved. The buggyness that we are experiencing is my rush to convert our site to vB 4.1 whilst our design team (professionally hired) completes a new redesign. I knew that my time would be limited, so I upgraded before having the time to fully try SB in a test environment, under every situation, every browser, every smart phone, screen display width, operating system, etc. The truth is, it is me and me alone who is working on the maintenance and programming of SB, and frankly, I have other things that occupy my time.
I have a blackberry myself (for the Dominican Republic) and I can't download Tapatalk for BB until I go back to the Dominican Republic, as the App Manager requires a cell connection, and not wi-fi. However, you should be able to search Tapatalk for ScubaBoard and it will be there. I use it on my droid, and have used it on iphone.
I know that the currently available mobile style (which isn't the same as before) now works on blackberry. I tested it.
Beyond that... this change over period requires a little patience for some of the long time users, whilst we go through this process.
While I don't want to see long time users leaving the site because of things that are minor inconveniences, I do at the same time see a large increase in SB's traffic, and our alexa ranking is also getting higher. Something is working, even if some people are somewhat put off by the change.
Let me suffice it to say... I'm doing the best I can with the limited time I currently have to make everything work.
