Greetings, other 1G owners on-the-edge,
Did you see any speed DROPS after installing 3.0? I have heard rumors (what this site is based around!) that since we have the slowest processor in the touch-device family, 3.0 will actually knock functionality down.
Also, I've heard (in the very prominent bugs thread in this same forum) that the wireless drops constantly and sometimes doesn't even connect - or even breaks the wireless controller's driver so that it doesn't even show up as having a network card!

The problem is that there are no reviews in the WWW that officially describe people in our particular device category (are there?) so we're all kind of stumbling about in the dark.
