Curious about how much space the apps and data on your iPhone, iPad or iPod touch is using? Or how about choosing which apps back up to iCloud? iOS 5 can help you with both, and The Mac Observer’s Melissa Holt is ready to show you how.

Along with the official launch of iCloud, Apple released iCloud Control Panel for Windows on Wednesday. The new control panel adds iCloud Photo Stream support along with contact and calendar syncing to Windows Vista and Windows 7.

Apple released Aperture 3.2 Wednesday, an update to the company’s professional photo management and manipulation solution that adds in support for iCloud and iOS 5, including iCloud’s Photo Stream feature. The update also includes other features, as well.

Apple released iPhoto 9.2 on Wednesday, an update to the company’s consumer photo management and manipulation software that adds support for iCloud and iOS 5, including iCloud’s Photo Stream feature. The update also includes support for new gestures, new navigation features, and a few bug fixes.

Apple has been meeting with movie executives in an effort to bring movies to its iCloud service, according to a report from The L.A. Times. Through iCloud, Apple currently allows users to access their apps, music, and TV show purchases on any iTunes-enabled device (iBooks can be accessed from any iOS device), and the company is now working on bringing Hollywood movies into the fold, too.

Apple released Apple TV 4.4 on Wednesday, an update for the company’s settop box that adds new content and support for iCloud’s Photo Stream feature. New content includes hockey games from the National Hockey League, as well as highlights, scores, and other NHL content. The company also added news and business commentary from The Wall Street Journal, new slideshow themes, support for Netflix subtitles, and AirPlay mirroring for iPhone 4S and iPad 2.

As promised, Apple released iOS 5 for the iPhone, iPod touch and iPad on Wednesday. The new version of the mobile operating system added an improved notification system, over the air update support, and sync over Wi-Fi support. [Update: The article was updated with Apple’s iOS 5 patch note.]

Along with AirPort Utility for iOS, Apple released its Find My Friends app Wednesday morning ahead of the launch of iOS 5. Find My Friends is a new iOS 5 feature that lets friends and family stay in contact and keep track of each other’s current location.

Apple opened iCloud to the public early Wednesday morning ahead of the release of iOS 5 for the iPhone, iPad and iPod touch. iCloud replaces MobileMe as Apple’s online data syncing and sharing service.

Apple released iTunes 10.5 on Tuesday, but one thing many users have been waiting for wasn’t included: iTunes Match. The patch notes made no mention of Apple’s iCloud-based method of storing and accessing all of your music files, but developers got a new seed for iTunes (version 10.5.1 beta 1) that did. That means the service is still waiting in the wings while Apple continues to work out more kinks.
