Amidst a sea of anticipation, Steve Jobs began his keynote speech at the World Wide Developers Conference in San Francisco on Monday. While the Apple CEO will unveil fresh updates to Apple's iOS and OS X software—the show-stealer is the company's new iCloud music streaming service. Stay tuned for updates for all the hardware and software updates announced at the conference.

2:54 Jobs introduces software that matches your own music library to songs already present in iTunes, which costs $24.99 per year.

2:44 Jobs introduces iTunes in the cloud. "Any music can be re-downloaded to any device for no additional charge," reports Mac Rumors. In demonstration, a Foo Fighters song is downloaded on an iPhone at no additional cost—because it's previously been purchased. For new songs, the app allows you to preview the new song. As soon as it's purchased and downloaded on the iPhone, it's transferred instantly to the iPad. Jobs reiterates that all the iCloud apps are free. "We want every user to take advantage of these... We're very excited about it" says Jobs amid applause.

2:39 Speaking about his "favorite" app, Jobs introduces Photo Stream. If a photos is taken, it puts the photo in a roll that appears on every device (iPod, MacBook, iPhone). It's also in sync with Apple TV, so the photos will appear large on your television.

2:20 Jobs has returned to the stage to talk about the iCloud. Jobs is now "talking about how the PC was the hub for your digital life, you put all your media on your computer," reports Mac Rumors. But keeping all of our devices in sync is "driving us crazy" says Jobs. "We're going to move the digital hub... into the cloud." It's going to work automatically and integrate with apps. "It just works" he says, amid cheers. E-mails, inboxes and folders will stay in sync across every device. Jobs has announced the that service is free—a big plus that many had not expected. "We've added wireless backup to the cloud," adds Jobs. iCloud is also keeping backups in the cloud. Below is a livestream of the event:

2:06 p.m. Amid rambunctious applause, Forestall welcomes developers to a new era. "We're living in a post-PC world" he says. As expected, software updates "are now over the air." No need for USB cords.

1: 58 p.m. Forestall introduces Reminders app. "Reminders apps allows for storage of multiple lists, with dates to remind you," writes Mac Rumors, amid roaring applause. "Can even assign location, 'Remind me to call my wife when I leave the convention today.'" He also introduced a reader app, which saves what you're reading similar to Instapaper. "How many apps does each of the new iOS features kill? Anyone keeping a tally?" remarks Paul Kent.

1:50 p.m. Scott Forstall, VP of iOS software, is now talking about Twitter integration on iOS 5. Twitter's been integrated with photo-sharing Apps such as Camera. "Can also tweet articles from safari, videos from youtube, locations from maps," writes Mac Rumors.

1:42 p.m. The discussion has moved to the "future of iOS" iOS 5, which got a big round of applause. As many predicted, the update includes notifications. Because notifications "interrupt you," Apple is unveiling "Notification Center." Any notifications on iPhones and iPads will be viewable at a central notification center. "The Notification Center has your missed calls, new e-mail notifications, push updates from apps," writes Wired. "Notifications are no longer interrupting. If someone sends you a text message, an animation from the top shows up. This looks kind of like HP’s TouchPad notifications."

1:39 p.m. The cost of OS X Lion is $30 and and is only available at the Mac App Store as a 4GB download.

1: 30 p.m. According to the Mac Rumors live blog, the discussion has shifted to a new update on Mac Mail. "Looks a lot like the iPad client, search is also improved. Looks a lot more automatic in regards to helping you intelligently search." As Gizmodo notes the email client also has options for different visual displays of your email.  "Mail also comes with search suggestions, like a search engine, and conversation view which keeps all messages, people, and attachments inline."

1:14 p.m.  Jobs enters the stage and introduces Phil Schiller and Craig Federighi to talk about OS X Lion. Federighi begins explaining how Apple's multi-touch features will be expanding across different aspects of Apple's software. "Craig’s giving a demo of these three features working together" live blogs Wired's Brian Chen. " Safari no longer has scroll bars because we can push the content with our fingers using the multitouch trackpad. You can also zoom in to the webpage by pinching. Smart Zoom: You double tap to zoom in, double tap to zoom out, just like on the iPad."
