Supposedly, one of the big "features" of 4.1 is that the performance issue is supposed to be fixed for iPhone 3G's. I'm curious to know what everyone's results have been. I run 4.0 for about a month before I had enough of the BS and just downgraded back to 3.1.3. I'd actually forgotten just how responsive it was on 3.1.3. I'm hesitant now to bother "upgrading" the 3G again as I see it more akin to handicapping my phone so that it will annoy me sufficiently to where I truly need/want to get a new iPhone4. I'm sure 4.1 is better than 4.0.x, but what I'm truly interested in is how it compares to 3.1.x.
