I finally received my Model B revision 2 today, at least I hope so. After opening the box, I immediately looked for the blue 3,5mm jack. The one mounted on my board however was black. After cursing for a few seconds -like most of you, I waited a really long time to get my hands on one of these- I noticed the mounting holes on the board and the '100' label next to the LED for the ethernet port. Both the mounting holes and the updated label should mean this is a revision 2 with 512 mb RAM, no? It's the colour of the 3,5mm jack that makes me wonder. I would like to know if someone could clarify this, before I pry open my existing setup.
