Recently I found this article on Mobile-Financial.com. It is indeed interesting and would like to share it across to people.

In my recent blogs I have been discussing the challenges that developers face building cross-platform applications for Smartphones. The biggest of these is the huge divergence among Smartphone manufacturers which makes cross-platform development almost impossible. As a result, developers resort to creating different code streams for each smart phone platform and continuously port features between them.
For the screen size issue there seems to be a general convergence towards 320×480 so developing an application that fits well within these boundaries should work well on most platforms. Worst case, the UI layout would need to be separated based on the phone hardware and the mobile application built to detect this and show the appropriate layout (much like how current web sites show different content based on the PC browser being used).
In summary, WebKit may be the solution developers are looking for in order to quickly create and deploy their applications simultaneously on many of the emerging smart phones. Of course this also assumes that the developer has studied their target market and determined that it is absolutely the high end smart phone user and that these users span the multiple platforms. If not it is still much more beneficial to focus on the platform most used by your target user demographic.
