If you own a iPhone and want to sync it with your computer over a wireless connection? Right now the only way to do is to jailbreak your iPhone and purchase "Wi-Fi Sync app" from Cydia Store for iPhone, iPad, and iPod touch.
But someday you might actually be able to do it without voiding your warranty.
Steve Jobs replied to an email of Rick Proctor, who asked if Apple will ever support synchronizing an iPhone with a Mac over WiFi.
Jobs said: "Yep, someday."
