We have written about the rise of mobile apps that can connect you to your corporate documents previously such as Rover and MobilEcho. Starting this week, there is a free app called Coaxion from Moprise which can access your Sharepoint, Dropbox and Office365 file repositories as well as easily perform real-time threaded conversations.

Mobile advertising company Medialets rolled out a new Universal SDK this week, which it says is its biggest release yet. The Universal SDK 2.5 for iOS offers support for third-party rich media ads, new ad formats and new creative capabilities, like social media sharing, email, SMS, add-to-calendar functionality and embedded maps.

Jailbreaking, the act of hacking an Apple mobile device to allow for the installation of unapproved, third-party apps, is often seen as a niche activity undertaken by only a small subset of users. But the truth is, when you're dealing with Apple devices, even a small subset equates to a large number. According to Jay Freeman, who runs the largest jailbreak app store Cydia, around 10% of all iPhones are jailbroken. In total, he says there are approximately 10 million jailbroken devices in the wild, including iPhones, iPads and iPod Touch devices.

And now, this rapidly growing user base will have their very own conference: MyGreatFest, the world's first convention for the jailbreaking community.

Over on Google's new social networking service Google Plus, Seesmic founder Loic Le Meur started a great discussion on the differences between HTML5 mobile Web apps and native iOS and Android apps. The question he raised is what can you not do in a mobile Web app? You can't do video capture, for instance, or push notifications, among other things. But what else? What are the real challenges here?

At last count, 87 comments from Google Plus users helped to fill in the blanks. The resulting discussion is remarkably similar to something you would see over on Quora, minus the comment threading and answer summary. For mobile developers, this is one discussion worth checking in on.

Germany's Federal Office for Information Security issued a warning today that iPhones, iPads and the iPod Touch have "critical weaknesses," the Associated Press reports. The malware is delivered by an infected PDF that can affect the user's device without them knowing. The same result would occur when a user visits a website with an infected PDF.

This is one of the first malware weaknesses discovered for iOS. Android has an increasing problem with malware and rootkits but so far there has not been a significant weakness exploited on iOS (not counting the 120,000 iPads that were hacked last year which was really more the fault of AT&T than iOS). Is this just the first drip of a coming wave of mobile malware?

JailbreakMe.com, the easy-to-use browser-based jailbreaking tool for Apple mobile devices has just gone live with version 3.0. What this means is anyone can now jailbreak their iOS device running the 4.3 software (or below, in some cases), including the iPad 2. There is no software to download on your computer; nor does your phone, iPod Touch or iPad have to be physically connected to the computer for this to work. Instead, all the jailbreaking is done via the JailbreakMe.com website, thanks to a PDF-based exploit.

In our continuing tradition of rounding up new mobile application releases we found interesting and/or exciting over the past month, we present you with this new list of apps for June 2011. Previously in June, we shared a list of apps that came out in May and during the first part of June, so be sure to check that post for some early June app launches.

This time around, we're again focusing on new (and notably updated) iPhone and Android applications, as well as a few iPad, tablet and cross-platform apps that caught our eye. As always, share which apps are your new favorites in the comments below.

Shortly after Google unveiled Swiffy, the Flash-to-HTML5 conversion tool designed for WebKit browsers, mobile app development firm appMobi launched a related utility called appFlash. This new tool takes advantage of Swiffy's capabilities, allowing mobile developers to convert app assets coded in Flash into native iOS applications.

AddThis, Clearspring's online content sharing platform, has just arrived in a format for mobile app developers to take advantage of, on both iOS and Android ( the latter in beta). "Everything is shifting to mobile very quickly," explains AddThis CEO Hooman Radfar. "Our community of 9 million plus publishers are building more and more for the mobile Web, and they want the same functionality for mobile apps."

With the new suite of tools including AddThis for the Mobile Web, AddThis for iOS SDK, and the forthcoming SDK for Android, that will finally be possible.

A new feature uncovered in the second beta release of iOS 5 is great news for Web developers. It seems that native-style scrolling will be made available to Mobile Safari through a new CSS property. When used, Web developers will be able to implement native-style momentum scroll in Web pages, allowing Web apps to function more like native applications do today.
