No shock: Apple has rejected that nifty Wi-Fi sync application that was submitted for the App Store. Good news is, it's now available via Cydia for any jailbroken iPhone for $9.99. Engadget contacted the developer by phone and here is his rejection explanation.
"While he agreed that the app doesn't technically break the rules, he said that it does encroach upon the boundaries of what they can and cannot allow on their store. He also cited security concerns."
