Any chance the updated mail app will include condense/expand of the mail folder list, or ability to select which folders get sync'd/included in the folder list.
Also, wondering if the new API's allow SBSettings type bluetooth/wifi/3g etc toggle bar or WiFiToggle type apps.

Apps folder is a welcome development for my unlocked iphone 4. It's getting harder and harder to sift through all my apps. I have to swipe through a few pages back and forth before I can get to what I'm looking for.
