Are you drooling yet?
Some highlights:
No word on improved battery life, though. Still looking.
One really cool feature, as reported by *the* unofficial source, MobileCrunch:
Anyway, a new feature that most will love is the Find My iPhone. It’s a service for MobileMe subs that, well, finds your lost iPhone and displays its location on a map. It could be a great way to keep track of your spouse too. When activated, you can message your iPhone with a number to call and it will sound a tone even if the phone is on silent. Or you can remotely erase all of the data on the phone.
Must. Have. It.
…but if I don’t have it, at least I can still get all the software upgrades.
