iOS 4 spotlight: iPod touch Wi-Fi stays connected when asleep -- iPhone too?
One of the more interesting notes on Apple's iOS 4 for iPod touch page is persistent Wi-Fi connectivity, so Skype calls or push-notifications can come through even when your iPod touch is in sleep mode:
There's no word on whether this applies to the iPhone as well (since cellular data is typically persistent anyway), but it would be a nice feature to have in all iOS devices -- including iPad, especially when roaming with data turned off, or even just to prevent the delays that usually accompany reconnecting to Wi-Fi based remote control apps.
