Apple has published financial results for the third quarter of its current financial year. It's announced record quarterly revenue of $28.57 billion (£17.7 billion) and record quarterly net profit of $7.31 billion.

In the quarter, which ended on 25th June 2011, the company sold 20.34 million iPhones (up 142% year-on-year) and 9.25 million iPads (up 183%).

US-based mobile payment service Square, which lets retailers use an Apple or Android device to accept credit card payments, has just raised $100 million in new funding.

It's also announced that technology analyst Mary Meeker is joining the board.

As promised, Apple CEO Steve Jobs has opened the company's annual Worldwide Developers Conference with a series of announcements.

The next version of the iPhone and iPad operating system - iOS 5 - will have more than 200 new features when it's released this autumn.

Taiwan's massive high-tech industry has long been synonymous with building gadgets cheaply for foreign companies. But at the country's annual technology convention, locally designed tablet computers are hoping to change that image by challenging Apple's wildly popular iPad.

After decades of making PCs at a discount for more well-known foreign companies, Taiwan firms are using their manufacturing experience to design their own machines.

Next week's Apple Worldwide Developers Conference will see the announcement of iOS 5, the next version of the iPad and iPhone operating system, according to a company statement.

In addition, CEO Steve Jobs will be unveiling a new 'cloud' service called iCloud.
