Success! I'm quite partial to the original view. There are a couple of ways to downgrade.
I have a computer that I hadn't used to back up and sync since the 2.98 update. I deleted the app from the phone, made a copy of the 2.91 .ipa file (for good measure) and opened iTunes.
Backed up and sync. Marked iHub to install in iTunes -> Apps. Synced again and voila... Back to 2.91 and the view that I like much better.
If you have updated iHub on your computer, you can drag the 2.91 .ipa file into iTunes. When it asks if you want to downgrade --> yes indeed.
