I had the honor to program the EcoChallenge iPhone application. EcoChallenge is a fun method to reduce your impact on the environment. You can participate in challenges with your friends to lead a more sustainable life.
The complete Objective-C source code has been made available at GitHub. This is your chance to take a look at what makes an iOS app work.
I created two exhaustive iPhone In App Purchase example projects. The first one shows how to use the StoreKit API in a stand-alone application. The second one shows how to integrate it into a server infrastructure. It includes also a basic PHP script for purchase checking and delivery on the server side. The source code is available for download. It includes some third-party libraries, please respect their licenses.

Images (especially JPEG ones) can contain Exif meta-information which specify the image orientation. The following Objective-C method normalizes the orientation of an image by rotating and/or flipping the image accordingly. This step is necessary when an image is loaded from a file before further image processing operations can be applied. I copied the idea and some code from gotow.net and enhanced it by supporting all possible values of UIImageOrientation.

I enhanced the PL2303 USB to Serial Driver for Mac OS X to be 64 bit compatible. The kernel extension compiles into an Universal Binary which can be loaded in Snow Leopard 32 and 64 bit mode. The installation package as well as the complete source code, based on version 0.3.1 of the original driver, can be downloaded from the links below.
Installation package: osx-pl2303.pkg
