Will be making the switch to the 9900 tonight
I am taking the plunge and returning to the dark side. Don't get me wrong I like the iPhone 4 but when I first played around with the Bold I knew it was the phone I had to have. It is an awesome phone I love the physical keyboard, the lack of apps and support for some of those may pose a bit of an issue but there are other substitutes. Also I have read syncing a Blackberry to an iMac is much easier with the newest version of the desktop.
As for the camera, I did a comparison in the store I was at and found that the iPhone 4 isn't much better than the bold. You would need that real keen eye to notice any difference, just like a 1080p tv compared to a 720p tv. I don't take a lot of pictures but I did find the dedicated camera button much more convient that having to turn on the screen and tap the icon.
