Steve Jobs, wearing his customary black polo-neck, yesterday gave the market a preview of Apple’s iPhone OS4 software. Over 100 new features will be available to iPhone and iPod Touch users when the software update is released around the middle of the year.

New features include

• multitasking for third-party apps
• folders to allow for better app organisation and access
• unified inbox in Mail, allowing users to see messages from all their email accounts displayed together in a single inbox
• fast inbox switching and threaded messages
• iAd, Apple’s new mobile advertising platform
• iBooks, Apple’s new ebook reader and online bookstore
• enhanced enterprise support, including better data protection, mobile device management and wireless app distribution

Not all features will work on all devices – for instance, multitasking will only run on the iPhone 3GS or third-generation iPod Touch.

Just announced a few days ago at the WWDC 2009 keynote, Vodacom have announced that the new Apple iPhone 3G S is going to be available in South Africa starting from July (following a US launch on June 19th).

Hailed as the “the fastest, most powerful iPhone yet”, the new iPhone 3G S (“S” for speed) just got copy & paste functionality, three megapixel autofoucs camera with video recording functionality, hands free voice control and a new tethering feature that allows you to use the iPhone’s internet connection on your computer (not yet confirmed to be available on Vodacom).

But all these are available thanks to the new iPhone OS 3.0 operating system, which is actually the most significant update the iPhone 3G S just got. It allows for MMSs, instant navigation thanks to the new built-in digital compass, and the ability for iPhone applications to directly address external hardware.

It looks like we’ll have to wait for it till July … right guys?
