Was it my imagination or did a mod post saying grid mode was on the iPhone app and now that post has gone?
i saw it...wth? 
The grid is only available for the Player, and this thread is about the Stage.
The Stage/Head/Rack has up to 1000 rigs in memory. That's not what you can display with the grid. It's a valid question if there's a good way to display up to 1000 items on a phone. So, to answer the OPs question, we are aware of that but there is no timeline or guarantee we will have something like this in the future.
If you need to see a list now, use Rig Manager Desktop.

You will never be able to see 1000 rigs at once. Of course, some sort of partitioning would be necessary, but that's not the core of the problem.
