[Croatia] Shout’Em, a startup from Croatia that lets you create your own microblogging network, has just launched their official iPhone app. While the Shout’Em platform was first intended to enable mobile social networking, the founders have since decided to ride the “microblogging wave” created by Twitter. With the launch of the Shout’Em iPhone and Java apps, they’re returning to their original focus on mobile.

The iPhone app has all the usual microblogging features, letting you update your status, add photos as well as add your location. The most important feature, however, is the support for multiple microblogging networks: Shout’Em, Twitter and StatusNet. For users that use two or more of these networks, the iPhone application could prove to be very useful.

If you’re looking for a Twitter application that covers all the essentials, the Shout’Em app’s price (free) is unbeatable. On the other hand, you might miss support for some of Twitter’s newest add-ons, such as lists. While the app doesn’t support lists or save searches, it does support some specific Shout’Em network features. One of them is the ability to have threaded conversations, for example.

Shout’Em is planning on launching several other mobile applications, including a Java application for users without an iPhone or Android phone. The apps should make using a Shout’Em network easier and – mobile, which in turn should help the company build on the already 10,000 networks that its users have created on the microblogging platform.
