So the list from apple's website is:
1) Cut, Copy & Paste

3) MMS
4) Spotlight Search
5) Voice Memo
6) Better Calendar
7) Buy Movies, TV shows, and audio books from itunes
8) Improved Stock App
9) Improved Safari
10) Tethering
11) Stereo Bluetooth
12) Automatic Wi-Fi Login
13) Notes Sync
14) Parental Controls
15) Ability to Login to iTunes Account
16) YouTube Login
17) Shake to Shuffle music
18) More Language Support
19) Find My iPhone/Remote Wipe
20) Run the Latest Apps
Of these what are really knew?? I would say 6,8,9, and 18 are "improvements" not new features. #20 is rediculus because of course you would be able to run the lates apps with the latest OS.
