For wi-fi sync, you have to plug in the phone to the computer, go into iTunes, and select "Sync over Wi-Fi" (or something like that ... I had to check mark something, but now my iPhone syncs over wifi)
Although I'm not a fan of these extra apps I don't need ... videos? Newsstand?
And while I like the local weather feature, why doesn't the iPad have a weather app or stock app?? Seriously, I feel like those would be great on the iPad given some extra functionality!
