iPhone and Android

Hey guys
I want to develop a game and make it portable to iPhone and Android.
Is it possible to develop in the default version and when I finish buy the licenses and export for both platforms?
If possible which considerations should I have?

Yes you can do this but you will have to consider that the input will react differently on mobile devices as well as the performance will be wildy different. It is also worth checking the license comparison page as some features on one device may not work on others.
