In this new version, as said above, comments have been seperated, you can update all and it comes with a widget....though not sure what it does...maybe displays updates?
I seem to have received the update today. Saw this posted yesterday, still had the old market. I now have the new one with the Widget. Galaxy S on Bell, stock 2.1.
I have a Droid X and the Market updated to version 2.07 today. I had a theme which made the market graphics black and white and they have been restored to the normal green and multi-colored.
I'm on an Xperia X10 which is stuck at Android v1.6. I ALSO have this silent Market update with all the features. It's pretty cool except that it appears to have forgotten that I've paid for any app on my phone! Updates all tell me to purchase them. Uggggh.
