I just read this article and realized it was more than a week old. It’s still important though, so here goes. According to the article, a person mailed Steve Jobs about wireless syncing of the iPhone with iTunes. Steve replied: “Yep, someday.”

Wireless syncing on the iPad (or iPhone) can already be done via a Jailbreak app (I’ll post a How To article about that tomorrow). Let’s hope we don’t have to wait till iOS 5 till we can officially/legally sync our iOS devices over WiFi. Could be a good addition to the iPad release of iOS 4 later this year.
