Apple has released a minor update to its MobileMe iDisk application for the iPhone, iPod touch and iPad. MobileMe iDisk is a free application that allows iOS device users to open, view and share files from their online iDisk storage. The application also provides the ability to continue playing audio files in the background on multitasking-capable iOS 4 devices. Version 1.2.1 fixes an issue that prevented package files such as Keynote presentations from opening in the correct application on the iPad and displays rotated images in the correct orientation when opened. The update also includes various stability and performance improvements. MobileMe iDisk is available from the App Store as a free download.
