iphone 4 just announced.

Another big difference from my 3 is the battery.
I have not charged it all since picking it up around lunch time yesterday.
Used it all afternoon into evening.
Left it on overnight.
Still have about 3/4 of the battery life.
I did have it connected for a while to the laptop while I restored by information and it did get a brief charge there but I still think this is quite good compared to what I had.
