Apple Mac is too much conservative regarding iPhone. There are pretty much sufficient restrictions on the development process of iPhone applications. And recently Apple has announced to restrict the developmental platform should base on Objective-C, C++, C and Java Script. This step blocked the development of other third party tools which several companies were offering to develop applications for iPhone in different languages and frameworks.
One of the third party frameworks was Adobe's development tools for iPhone, which were used to develop flash applications for iPhone. But after this move Adobe stops the development of these tools although the previous version would be shipped with Adobe CS5. A similar framework is Mono which provides a compact framework for iPhone named Mono Touch. It is very interesting to see that Mono Touch applications wont affect very much as this link says. I was expecting the same for Mono Touch also, but it looks that Mono is more integrated into the native APIs of Mac and iPhone that's why they will take the advantage of being on the platform.
This was the move from Apple, what from Adobe? This is the move from Adobe. Adobe and Google partner to bring Flash and AIR technology to Android. Android as you know is the famous and creating its market quickly, new smart phone OS which is based on Linux and Java. While iPhone OS is proving itself too much conservative, Android is proving its flexibility. The other advantage is that it is installed on multiple phones, devices while iPhone OS is used on iPhone only. Adobe and Google's partnership is not ignorable in the present scenario when Apple just has banned somehow the entrance of flash on iPhone. Although they have (at last) provided a framework for flash on Mac OS X.
The scenario is going to be very interesting in the coming days. Flash is something which was always a powerful RIA framework and multimedia format. Microsoft Silver Light is lacking behind somehow now and Java Flex is still in coma. We do not hear what is going on under the cover in Flex. So lets wait and watch, what's gonna happen.
