Well, after playing around with iOS 4.3 for a bit now, I can tell you, the hotspot is small potatoes.
The iTunes Home sharing, Nitro JavaScript in Safari and the Airplay enhancements alone, are flat out awesome.
Using my Apple TV, I'm playing music from my iphone through my home theatre's audio system, watching video right from the phone onto the TV, this is awesome.
Control Apple TV, right through the iPhone4, using the phone as a remote control with the Apple Remote app downloaded free from the App Store.
Can gain access to the entire Music Library in my Macbook Pro, as well as shared video, and photos, using the iPhone4 and can play them or see them on the iPhone. Using my iPhone4, I can access and play anything in iTunes on my Macbook Pro. Plus streaming audio from my favorite stations, and video.
This means you don't have to store as much music on the phone itself. You can access it using the phone, and play it through your phone, if you want or through your TV or powered speakers, or home theatre.
I hope you guys get this soon, because it definitely makes the iPhone4 an even more awesome device than it is already.
Here's to hoping that you guys get it ASAP, as in next week.
I cannot imagine Apple making you wait any longer than that. It would be criminal for them to make you wait much longer than that, because this update, is just that good.
Good luck. It's definitely worth whatever wait you guys end up enduring.
