The headline features (Genius, ringtones, app organization via iTunes), don’t excite me that much. I use Spotlight to find apps, rarely use any special ringtone (let alone one I have paid for), and I used the Genius once in iTunes and forgot about it. I’m somewhat disappointed at the lack of an Energy Saver settings page, but at least the following features seem useful.
Remotely lock iPhone with a passcode via MobileMe
I guess this means that you don’t need to put a passcode on your phone before you lose it. Maybe you can push a passcode to the phone after you lose it, so you don’t have to deal with the hassle of unlocking the phone all the time. We’ll have to see what this is like in practice.
Use Voice Control on iPhone 3GS with Bluetooth headsets
It’s not clear how Voice Control would be invoked in this situation. If you have to hold the home button on the iPhone, then you still need to fish it out of your pocket or purse. If, on the other hand, you can push a button on the headset, this could be great.
Paste phone numbers into the keypad
I just tried doing this the other day and was surprised it didn’t work. Now it will.
