Apple has just released the first developers preview version of iPhone OS 4 Beta, along with SDK for iPhone and iPod touch. Only members enrolled in the iPhone Developer Standard or Enterprise Program can access these bits of iPhone OS 4 and SDK by signing into Apple Developer Connection.

Apple today has unveiled the new iPhone OS 4 firmware in a preview event, held at their 1-Infinite loop campus in Cupertino. This announcement added lots of new features for both users and developers. Here is a sneak peak at what the new version of OS is going to offer.

Apple is all set to unveil iPhone OS 4.0 tomorrow, at an event which will be held at their One Infinite Loop Campus in Cupertino. There has been lots of talk lately about all the different features that might become a part of this major OS release. Here is a compilation of what to expect from iPhone OS 4.0.

We all knew that iPhone OS 4.0 firmware was going to be unveiled this year, but not as soon as this. Well folks, it is now official and confirmed, they are going to announce it on April 8th, right after the big bang launch of the iPad.

As we have already informed you earlier today that Apple has released the final version of iPhone 3.2 SDK, including iPhone OS 3.2 (or iPad 3.2) for iPad to developers. This version of OS is compatible to work with iPad only. You can get your hands on the SDK now and start exploring the amazing things that you can do with it before the actual device, which ships on April 3rd.

According to a recent job posting, the Cupertino based company is looking for a engineer to lead a group of software engineers in order to bring iPhone OS to new devices and platforms. The job description is as follows.

In the midst of all the iPad hype, what everyone seems to have missed was a leaked image of the next generation iPhone by Apple in one of the leaked images of iPad, which Engadget had posted just a few hours before the official announcement. As you can see from the image below, the form factor mostly remains the same as iPhone 3G/3GS except for the few finer improvements here and there. But what we can expect from Apple is some drastic changes underneath the shell with a faster processor, a 5 megapixel camera with LED flash, camera on the front for video conferencing, support for WiFi-N standard and so on.

As was predicted, CEO of McGraw-Hill has confirmed in an interview to CNBC today that Apple is going to announce their Tablet on 27th and it will run on iPhone OS. Terry McGraw, who is the CEO of the famous publishing company further went on to confirm that they “have worked with Apple for quite a while” and that it will be based on the “iPhone operating system”.

Folks over at BGR have got hold of exclusive list of features, which they have been told are confirmed to be a part of the upcoming iPhone 4.0 Firmware. The next iPhone firmware is rumored to be very close, if not same as the OS on the rumored Apple Tablet. It is said to include multitouch gestures OS wide, multitasting (finally yay!), lots of UI changes including a refreshed homescreen! and more syncing options for the native contacts and calendar apps.

According to this report from Clayton Morris of Fox News, we’ll see Apple Tablet, the next-gen iPhone software dubbed as “iPhone 4”, and iLife 2010 next week at the special Apple event in San Francisco. The next-generation iPhone 4G however wont be the part of the event. Clayton, who talked to a source at Apple this morning confirms that the January 27th event will mainly focus around these three products.

It is now confirmed. Apple has just sent out loads of invites via email for the long rumored special event, which is now scheduled to be held at 10 AM PST on January 27th, at the Yerba Buena Center for the Arts Theater in San Francisco.

An anonymous iPhone app developer has dropped a hint today to CNET, stating that he has submitted an updated version of his app for iPhone OS 4.0 to Apple App Store for approval. This hint surely indicated towards a possibility where Apple might have already sent out the said firmware to a selected pool of testers.
