While no huge press release announcement came with this news it's certainly newsworthy in our opinion. RIM has acquired yet another company dedicated to development and more specifically, mobile web development. Granted, the name may not sound familiar to a lot of people but tiny Hippos is the company behind the Ripple Mobile Environment Emulator, a tool designed to test and debug cross-platform mobile applications.
The intent here of course, is to bring BlackBerry support to the Ripple and as such offer developers another set of tools to be able to debug and test their applications when preparing them for release on the BlackBerry Platform. Although I'm sure over time tiny Hippos role will certainly be expanded within Research in Motion, much like we've seen from their previous acquisitions.
