They mis-underestimated the clamor that has arisen from the 3.2 mil customers for things like multitasking and folders. I hope they are true folders, not just the "stack apps to produce a folder of apps" that has been discussed. Although that would be very useful.
What we need is the ability to build new custom folders related to each app that has/develops/imports data/photos/ & etc.. It is not clear that is what we are getting. Does anyone have any feedback on the 4.x that is in the iPhone 4?
