Is it just me or are apple making more dumb mistakes lately? There's this and that ajax caching issue from a month or two ago. Perhaps I'm just having selective memory?

I think Apple has always had the tendency to make dumb mistakes, but I will say that I think reporting on it has changed. Remember all of the jokes about "It's not a bug, it's a feature" back when Jobs was there? Apple is by no means immune from mistakes and I don't think they ever were.

I dunno, how crummy the App Store has become is a perfect example of this. The App Store is one prominent way they make loads of money and build loyalty to the ecosystem, and yet it is a shitshow on IOS6...the responsiveness is as bad as I've seen on non-iOS software, but for me, the two really inexplicable failures are:

1. the use of modals to show individual apps on the iPad. So if you get to an app page and accidentally touch outside the modal, the app page disappears and you have to go back to Safari to find the link that brought you there.

2. On my brand new iPod, the Genius View has never NOt crashed. I know Genius (and most of Apple's search services) are poor to begin with, but it's a prominent button on the nav. How does it just not work on a brand new device?

3. I'm also guessing the lack of a light sensor on the new iPod was the result of a screwup in the dev cycle...I would've never guessed that its absence would be such a deficiency but when you can't see a single thing on the iPod merely because you stepped from indoors to outdoors...to the point where you have to go back inside to adjust the brightness...that's just infuriating.

I can't remember the last time I've been infuriated by an Apple device...I feel infuriated all the time with my expensive Sony camera and how its video button is right where you can accidentally bump into it when shooting a pic...which prevents you from shooting a photo. The last few Apple devices I've had (two laptops, 2 phones, 2 iPads, countless iPods) have always been satisfactory in terms of polish...not iOS6 nor the new iPod touch

Now that explains the sudden spurt in my 3G data usage in the last 3 weeks. This forced me to switch off my 3G :(. Hope Apple releases a fix soon

We (PRX) haven't seen any evidence to show that it is still an issue in iOS 6.0.1, so you should be all set if you've upgraded, or an upgrade should fix it. If you are upgrade already and seeing overuse, please comment.

I was (and still) using iOS 6.0.1 when I started seeing the surge in data usage

Author of the post here, happy to answer any questions. I'm pretty confident in our findings here, and some of the behavior is just bizarre.

I saw similar behavior when I was working on the backend for an IOS app.

We were able to track it down to a retry mechanism for streaming content when the server was responding too slowly. Maybe you are running into something similar.

Ever since I started using Apple gear, I've found apple's software quality is way below hardware. iTunes on Windows was always a disappointment.

Hmm, so this explained my 3G data overage last month. I have 6GB/month of data, and usually I'd be using around only 700MB. But last month my iPhone 4S (running iOS 6.0) consumed nearly 8GB in total, resulted in quite some overage fee.

Should I ask Apple for a refund for this? :|

I'm seeing this line in my log as well, this person downloaded about 750MB and they don't seem to be on iOS 6.0.

Wonder if the CDNs don't have any safeguards in place to avoid single client downloading same resource multiple times?

That doesn't seem practical. How would they know if it's the same client? Just watching for multiple requests from the same IP will result in a lot false positives (e.g. most college students will be SOL). And what would they do if they could detect it but the client didn't realize it already had the file? Just drop the request?
