Mobile analytics firm Flurry is out with a new report that examines the revenue generation capabilities of free-to-play (aka "freemium") games versus paid ones. The conclusion was somewhat surprising: freemium games actually make more money. As of June, freemium games accounted for 65% of the revenue generated while premium games accounted for just 35%.

But this hasn't always been the case.

Why did Apple put out a press release today about reaching the milestone of 15 billion downloads? Maybe to distract you from the other news about how it just lost the rights to the term "App Store" in a high-profile lawsuit against top competitor Amazon.

Well, guess what? It worked! Look what our headline reads!

Still, it is an impressive number, and one that puts competing app stores to shame. And Apple had even more new numbers to reveal today, too.

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.

The market for mobile application development services, which includes things like app creation, management, distribution and extension services, will grow to $100 billion by 2015, according to a new report from research2guidance. Currently, the number of applications developed by third parties is at 66%, but the analyst firm believes this will increase over the next few years as more companies want to publish for mobile, but don't have in-house resources to do so.

Popular iPad magazine app and Apple's iPad App of the Year Flipboard has just released a new version featuring a handful of updates, including one which has the company rethinking a user's first-time experience with the application. Now, instead of having to configure Flipboard with your favorite sources for online news, photos and other topics, a new content guide lets you immediately start browsing well-known websites formatted in an easy-to-read magazine-style layout.

Flipboard has also added built-in search, LinkedIn integration and has reformatted how the links from Twitter appear. But the company's biggest update is still yet to come.

Mobile application search and discovery service Chomp just released its latest app search trends report, and tucked away in the data is promising tidbit for Android app developers to note. There has been a slight, 2% increase month-over-month in the number of paid applications downloaded on Android.

In May, a pair of reports painted a troublesome portrait of the app economy on Google's Android Market. First, mobile analytics firm Distimo found that the vast majority of paid applications were downloaded less than 100 times, and a few days later, mobile search firm Chomp reported that 97% of all Android downloads on its service were free apps. For developers, the takeaway was that if you want to generate revenue for your mobile application, you have to think outside the "paid app" box.

However, that's not always the case. Although it may be a rare example, SPB Software has managed to have a revenue-generating hit on the Android Market with its SPB Shell 3D application, which earned the company $750,000 within its first three weeks of availability.

Google recently made a slight change to its Android Market ratings system for the Web, which brings it more in line with competitors like Apple and Amazon. Now, users browsing for apps from a PC Web browser will see more how many people have given an app a particular star rating, as opposed to just an average of all the ratings an app has received.

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.
