• Note syncing is pretty great, even if it is almost two years late
• You can sync notes through MobileMe as well as through iTunes
• Your call list now shows the location the call came from (was hidden inside each call screen before)
• Spotlight is great and speedy unless you have nine pages of apps, then it's SLOW
• MMS is currently broken (Could be because of AT&T plan, not because of the software - Thanks commenter!)
• There's a new MobileMe locator option to locate your phone from MobileMe. This is possibly so you can see where you left your phone, or maybe even where the thief who stole your phone is? Not sure.
