Found something maybe interesting?

I have Android System Info installed from the market. I noticed under ram it says 394mb Max. I thought the Evo had 512mb?

Probably some held back for the system? Has to be installed somewhere.

That should be internal memory storage for system. Not the ram.. Weird I dunno, but usually it should show the max being 512mb. Oh well!

it shows max usable by the system, the rest is taken up by the OS parts and obviously isn't part of the usable portion.
