Unity 3.5 contains new particle, lighting and rendering effects to improve the overall look of iOS games created with the engine, on top of improvements to AI and pathfinding code for enemies and memory and performance enhancements. The updated SDK now also allows developers to export their work to Flash, and to create a native client that can be played within Google Chrome without the need to install an add-on.

Reports are surfacing that Apple’s iOS 5.1 software update will be released publicly about one month from today. Leaks of operator profiles set to be sent out to various iPhone carriers point directly towards a March 9th release date.

Napkin Studio’s David Stanfill has been hard at work developing an OS X client that will allow for AirPlay mirroring from iOS to OS X, something that is currently unsupported. Stanfill’s decision to develop such a client and the technology behind it came from his desire to find a better way to demo his iOS applications during online meetings and to be able to record live video of the apps as they are being used.

NetMarketShare’s desktop Operating System Market Share metrics for January 2012 show the Mac OS gaining a minuscule three tenths of a point on the month, with Windows falling back slightly. In the Mobile/Tablet category, the iOS was still well out in first place, and recovering some of the ground it gave up in December.

A new project entitled iOSOpenDev will allow something that many iOS developers should be excited about: the ability to create unofficial third-party apps, tweaks, themes, etc. right from within Xcode. The project, created by developer Spencer James, is nearing completion and public release, and is almost certain to gain a lot of hype among App Store developers interested in creating something for the jailbreak community.

If you’ve jailbroken your iDevice(s), you may be aware of a really cool tweak in the Cydia Store that provides the ability to multitask through touch gestures alone. This tweak, called Zephyr, has just been updated to version 1.1, bringing with it the ability to also navigate to the home screen without having to use the home button.

If you care about jailbreaking and its future within the U.S., you should be worried about the fact that the exemption which ruled that jailbreaking a handset was not a violation of the Digital Millennium Copyright Act (DMCA) will expire later this year. Back in 2010, that exemption made it clear that jailbreaking a handset such as an iPhone is completely legal in the United States, even though it was strictly limited to “handsets” and did not cover things such as tablets or video game consoles.

An untethered jailbreak is now available for both A5 iDevices: the iPad 2 and iPhone 4S! Thanks to the efforts of iOS hacker pod2g of the Chronic Dev Team, this untethered jailbreak comes through a new tool that goes by the name of Absinthe A5, based off the team’s popular Greenpois0n software.

whited00r—which provides users of discontinued iDevices such as the iPhone 2G/3G and iPod touch 1G/2G features found within versions of iOS that these iDevices are unable to support—has been updated to version 5.1. The update mainly adds features from within iOS 5 to these iDevices, bringing them up to date with newer iDevice models…with a few exceptions, of course.

Yesterday, we reported that the developer pod2g demoed on video the iOS 5.0.1 untethered jailbreak on an iPhone 4S. The video showed the iPhone fully running the untethered jailbreak without any hiccups while running the Cydia app. Now, the infamous Chronic Dev hackers have posted an image of an iPad 2 with Cydia v1.1.3 running iOS 5.0.1. The hacker Pod2g mentioned in the caption that its full release is only days away.
