iPhone 4 Makes Sour Apples?

As the iPhone 4 reviews begin to gush (and I do mean gush) from the professional review sites I'm beginning to hear grumblings from folks just now getting theirs. It appears as though you can't activate them unless you're running OSX 10.5.8 and have iTunes 9.2. Now while I understand it's human nature to resist change, I thought you Mac folks were on the cutting edge. I'm running 10.6 on my DELL for goodness sake...
