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.

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.

Apple will release two new iPhones come September, according to speculation from analyst Chris Witmore of Deutsche Bank: the iPhone 5 and the 4S. The idea makes sense, as it would allow Apple to simultaneously address both the mid-range smartphone market with a more affordable device while also providing a more expensive model for the high-end.

However, the theory appears to be nothing more than that: a theory. Meanwhile, a separate report from Morgan Stanley analyst Katy Huberty states that production for the next iPhone will begin in August.

Registered Apple developers who were unable to attend this year's WWDC can now watch what they missed over on Apple's Developer Center website. Apple has posted 109 WWDC session videos online, which include both videos of the presentations and the accompanying slideshows.

According to a new report from analytics firm Distimo, the iPhone app download volume in Asian countries, led by China, has seen significant increases over the past 6 months, even as Western markets saw decreases. And China is now the second largest market in this area, after the U.S.

However, even though the numbers of downloads are increasing in this region, the proportion of paid downloads and overall revenue is lagging behind both the U.S. and Europe. That means developers wanting to expand their businesses into Asia need to have other monetization plans in mind, such as advertising.

According to a new report from network management and video optimization firm Bytemobile, mobile video now accounts for between 40% to 60% of the total mobile data traffic on operators' networks. Half of the video consumed comes from laptop computers, iPhones, iPads and Android devices, the company found.

But here's an interesting side note to that data: When broken down by device, iPhone users see more video data traffic than those on Android, or even on laptops.

I very rarely review a single mobile app these days - we prefer to do mobile app round-ups here on ReadWriteWeb - but I'm going to make an exception this time for Photogram. This new iPhone application, launched just yesterday, is deserving of a mention, if only for catching my attention among a sea of mobile photo app startups.

From the description, the app seems somewhat basic, maybe even a little boring: share photos via Facebook, Twitter or email. But it does so with a simplicity, elegance and ease that I've often found lacking elsewhere.

App monetization and distribution service provider Tapjoy has just announced the launch of a $5 million fund to help iOS developers port their existing applications to Android. The news comes on the heels of Apple's policy change, which affected all apps that used Tapjoy's pay-per-install advertisements. Apple's decision, said Tapjoy at the time, "is destroying the user experience and threatening the entire freemium model."

Now, the company has a workaround: move to Android.

Today, Yahoo introduced two new search tools, one a new online search engine for finding new mobile applications, and the other a mobile app called AppSpot (iPhone, Android), which does the same. According to a Yahoo blog post, the goal of these new services is to help you better sort through the some 425,000 mobile applications on the iTunes App Store and the 200,000 apps on Google's Android Market so you can find the app you need.

But will Yahoo's efforts prove better than any of the existing services that already do the same?
