Oh dear. It’s no secret that out of all the major mobile platforms, RIM’s BlackBerry OS is the easily one of the most difficult to develop for, but even with that in mind, we didn’t see Skyfire completely abandoning their BlackBerry client, even if they haven’t worked on it in months. In a blog post Wednesday afternoon, Skyfire’s CEO, Jeff Glueck, announced that his company has ceased all work on the BlackBerry version of their popular browser in order to focus on Android. Citing a poor developer environment with inconsistent and fragmented APIs, Glueck apologized to those who have been eagerly awaiting the release of the browser while vowing to return to development provided BlackBerry OS 6.0 delivers on RIM’s promise to bring much needed improvements from a developers perspective. Of course the release of OS 6.0 will see RIM release its WebKit-based browser, but then a little healthy competition is good for us consumers, right?
