iOS 5 Beta 2 is here. Of course there's lots of bugfixes—and wireless syncing!—but we should know what else is inside shortly. [Apple]
It's still wired syncing in a way because you have to hav it plugged into a power source for it to sync, so there's not a big difference between plugging it into your computer or a wall charger.
I know Apple wants to protect battery life, but this is just getting stupid. I only plug my iPhone into the wall at night when I go to sleep. Also sleeping at that time; my computer.
