iAds would go live for "all iOS 4 devices" on Canada Day, and sure enough, they look to be popping up today. One eagle-eyed tipster has already found one within the 'Mirror: for iPod and iPhone' app, shown above. It's certainly quite a bit more visually soothing than some other ads we've seen, but we aren't here to judge -- instead, we'd love to hear your take on it. Have you seen any iAds creep into your apps today? Whatcha think of 'em? Let us know in comments below.
Update: Looks like a Nissan Leaf iAd has debuted as well; the vid's after the break of that one.
Update 2: Oh, and this is just for North America for now. Everyone else will have to wait. Crushing, we know.
