And then it was all Webkit! RIM just announced that it will be using Webkit-based browsers for the new BlackBerry devices. This was a smart move; seems obvious and will certainly excite the competition with the iPhone. Thinking about this from my POV, this makes web-based mobile development twice as simple as now, there is almost just one browser to support: Webkit. However there are very distinct user experience and interface elements for iPhone-based applications (in all Apple products for that matter!) I’m not a BlackBerry user, so I’m not sure how those UX elements would translate, but I suspect they will not. Therefore, in many instances, we may still be up against two separate codebases for the app interface.
