Looking to save money on your wireless bill? Have the new iPhone? Maybe you should start making video calls instead. With this week's launch of the new iPhone 4 and its accompanying software, the Apple smartphone now enables a video calling feature by way of a new application called "FaceTime." And apparently, these videos calls, unlike their voice counterparts, are free.

Ahead of Thursday's release of the new and improved iPhone 4, Apple is today launching a series of software improvements collectively known as iOS 4 to owners of older generation iPhones and iPod Touch devices. iOS 4, the updated form of the iPhone operating system, brings over 100 new features, some big - like folders for apps and unified inboxes - some small - like home screen wallpapers and threaded email - and some - like multi-tasking - which your old iPhone may not be able to run at all.

Online tracking firm Quantcast has just released new data that shows mobile operating systems' current market share in North America, with the newly renamed "iOS" (originally called "iPhone OS" - the OS powering the iPhone, iPad and iPod Touch) in the lead...by miles. The Apple mobile OS dominates its competitors with a huge chunk of mobile market share, at 60%.

But don't let these numbers fool you. It's not how much or how little of the mobile landscape each OS has claim to, but how fast this picture has changed over the preceding months. The real winner here is Android, the OS whose rapid gains have come at Apple's expense.

You may have heard that a little company called Apple will be announcing, among other things, a new iPhone today. Supposedly called the "iPhone 4" (or maybe the "iPhone 4G? HD?"), for the first time ever since the product's initial debut, news of the company's latest gadget may not be met with same levels of adoration granted to Apple's previous announcements - and not just because photos of a stolen iPhone prototype spoiled us by giving away all Apple's secrets in advance.

No, today Apple is finally facing some tough competition in the smartphone space from none other than its former friend and partner Google, whose Android mobile operating system can now be found on a range of devices including the new must-have phone, the EVO, as well as the Droid, the Nexus One and more.

In a matter of hours, we'll find out if the iPhone can still compete.

The long-awaited iPad/iPhone jailbreak has finally arrived, allowing anyone with an iPhone, iPod Touch or even the brand-new Apple iPad running the newest versions of the iPhone Operating System the ability to unlock their device and install unapproved, third-party applications.

Unlike Google's Android Market, the app store for Google-powered phones, Apple's iTunes App Store is tightly controlled with only "approved" applications allowed access. But for jailbreakers, the term used to describe those who hack their devices, hundreds more applications are immediately available, allowing you greater control and freedom over the hardware you own.

Just over six months ago, two Android handsets, the HTC Dream and HTC Magic, accounted for almost all of the Android traffic on mobile advertising service AdMob's network. As the Android market has grown, so has the diversity of devices. Today, 11 different device make up 96% of AdMob's Android traffic. According to AdMob's latest metrics, old versions the Android operating system - versions 1.5 and 1.6 - still account for over 60% of all the Android traffic on AdMob's network. Devices running Android 2.0 and 2.1only make up about 35% of all the traffic.

So before the purists go off the deep end, fuming about the iPhone OS 4.0 announcement today, let's just concede one point - it isn't truly multitasking. Apple announced "Multitasking" with seven key points, one of them being "Fast App Switching", and this is what they meant for much of multitasking.

But here's the thing. For some of the most exciting multitasking-oriented things we've wanted to do with our iPhones, the new OS will indeed offer true multitasking - and for that we're fairly excited, to say the least.

During a presentation on Apple's Cupertino campus this morning, the company's CEO, Steve Jobs, announced the next version of the iPhone operating system: iPhone OS 4. Apple will release a preview version to developers today and plans to release the OS to consumers in the summer. Among the new features in the OS are multitasking with the help of a new set of APIs. Developers will get access to over 1,500 new APIs, and users will see over 100 new features.

Jobs also announced that Apple has already sold 450,000 iPads.
