Good day. I would like to know what you will advise for developing games and applications for iphone / android, for developers who know both C # and actionScript. What is easier to learn, more promising, easier to develop. What are the pitfalls of these platforms. More interested in the development side of 2d games. Separately, I would like to ask if it is possible to develop on flash on box2d or other physics engines and transfer this application without any extra dancing to iphone / android. It is also interesting how the installation of flash games on iphone / android looks like does it pass without complaints, or does it require installation of plug-ins, specific deployment, or any other thresholds for quiet use by the end user? It is also interesting, does the accelerometer support well on these platforms? Thank.
