Address Book security
After the news that Apple are going to add a location services style prompt to accessing address book data, Dave Addey has written about the larger problem of ownership of contact information.

Hashing for privacy in social apps
After all of the address book and privacy issues over the last couple of weeks, Matt Gemmell has written about the principles of hashing. It is very likely that as a subscriber here that you already know most of this but just in case you don't this is a great, mostly non-technical overview.

A one finger rotation gesture recognizer
I am usually the person saying that you shouldn't go creating your own gesture recognisers (for usability rather than tech reasons) but I think this article by Thomas Mellenthin this is a perfect example of where a custom gesture is exactly the right choice.

Nick Harris with some code for recreating the slide out navigation seen in several iOS UIs recently by animating an image view with a screenshot around.

Download bots were the “well-known secret” of the app ecosystem
I love the idea from this of Apple basing chart positions on not only download numbers but also usage data. To see the top 25 most used iOS apps as a category on the store would be amazing, I wonder if Apple will ever give us an official analytics API and do this.
