The day has come, millions of iPhone, iPad and iPod owners finally have the chance to experience the new iOS 5 software from Apple, bringing a large number of new features, services and bug fixes.

As with every major Apple release, the new software provides users with completely new but also vastly improved features and services. With the release of iOS 5, Apple brings enhanced notifications to iOS devices, iMessage, wireless updates and iTunes syncing, widgets, Twitter integration, improved camera and photo support, newspaper and magazine subscriptions, enhanced reminders and a whole host of new and impressive features.

The new iOS 5 update will most likely be one of the last people have to make via iTunes, because the new software allows users to update their iOS devices via a new Software Update feature in the iOS software itself, downloading updates via the device’s WiFi connection and automatically applying them without the need for a physical connection.

Coupled with that is Apple’s iCloud service, which will take care of all of your music, photos, documents and other important files, wirelessly syncing them between your iOS devices but also your Mac – no longer relying on a signal piece of software to store and update data and apps on your device.

To apply the update, connect your iOS device to your iTunes installation and check for updates. Do make sure to backup your important data and files before you do, just to be sure, but once you have downloaded the update, the software will take care of the rest. Once installed, you can all but kiss goodbye to iTunes for device updates, making you love your iOS device even more.

Apple’s Steve Jobs has resigned as CEO of the company, reports the company. Apple’s COO Tim Cook has been named as a replacement and Jobs has been named Chairman of the company’s Board of Directors.

In a publicly released letter, Jobs says that he can no longer meet his duties and expectations as CEO of the company and that he has resigned as the CEO of Apple. In the letter, he also recommended Apple’s COO Tim Cook as a successor, which does not come as a surprise to those of us who have been following the company.

As the company’s interim CEO in recent  months as Jobs has been absent due to health concerns, Cook has been the clear choice to those outside Apple for some time now, and apparently that choice had been made inside Apple as well as Jobs says that this is according to the company’s succession plan.

“Steve’s extraordinary vision and leadership saved Apple and guided it to its position as the world’s most innovative and valuable technology company,” said Art Levinson, Chairman of Genentech, on behalf of Apple’s Board. “Steve has made countless contributions to Apple’s success, and he has attracted and inspired Apple’s immensely creative employees and world class executive team. In his new role as Chairman of the Board, Steve will continue to serve Apple with his unique insights, creativity and inspiration.”

“The Board has complete confidence that Tim is the right person to be our next CEO,” added Levinson. “Tim’s 13 years of service to Apple have been marked by outstanding performance, and he has demonstrated remarkable talent and sound judgment in everything he does.”

Steve Jobs has been one of the most intense and charismatic executives of any company in recent years and his leadership has propelled Apple to new heights. This is a dramatic announcement and we will have continuing news on the ramifications of Jobs’ move to Chairman and the replacement of his role at CEO by Tim Cook.

Apple is more worried about Facebook as a competitive threat than any other tech company, according to a source who works with Apple.

Our source was surprised since it would make more sense for Apple to worry about other companies. Google has Android. Microsoft dominates the PC business. Amazon is threatening to enter the tablet space.

But Facebook is coming on like a freight train in a space Apple doesn't really understand and it's not willing to play nicely with Apple.

Another source who works with Facebook backed this up earlier this year, telling us that Apple hates Facebook because it worries Facebook could co-opt the iOS platform thanks to its strong user base.

A few other reasons we think Apple would fear Facebook:

It was burnt once by Google, so it learned its lesson: When Apple negotiated with Google to get Maps and search on the iPhone, it thought it was starting a great partnership. That didn't last, as Google built Android, which is now beating the iPhone in market share. Facebook is equally ambitious, and there's reason to believe it's going to build its own mobile OS.

Apple doesn't do social (or the web) particularly well: Apple understands the PC business, and therefore Microsoft. It gets the mobile business and Google. It gets Amazon's entry into tablets and its digital media business. Social? Apple doesn't get that at all. It doesn't really do social.

Facebook credits could be a threat to iTunes: In the long term people will be buying virtual goods, digital media, and real goods through Facebook. Facebook is already encouraging developers to work around Apple on its web platform.

Facebook has 650 million users and growing. Just like Google is worried about Facebook fencing a big portion of the world's population, Apple should be worried about Facebook controlling hundreds of millions of people. It's a platform war out there, and Facebook is in a good position.

Whatever the case may be, we're guessing something happened when Apple was negotiating with Facebook over Ping that opened its eyes and now it's keeping its eyes on Mark Zuckerberg.

Steve Jobs is probably one of the most polished presenters in the world. He doesn’t use any bullet points in his presentations, his keynote addresses are free of any jargon, there are very few words in the slides but they have photographs and headlines that are hard to forget (everyone still remembers “the world’s thinnest notebook,” a phrase that Steve used to describe Macbook Air).

If you like to learn some of the techniques and styles that make Steve Jobs such a great presenter, here’s some excellent advice [video + slides] from Businessweek columnist Carmine Gallo, who is also the author of the book -- The Presentation Secrets of Steve Jobs.
