Hello! I have been reading about Adobe Flash Builder and Flex SDK, and have three questions:
1. What is the difference between Flex and Flash Builder?
2. Can you develop mobile apps using Flash Builder and/or Flex?
3. I currently own Flash CS4. Can you develop mobile apps using it?
Thank you very much!
1. Flash Builder is the IDE, Flex is the SDK
3. You should use Flash Builder 4.5 as it has specific enhancements to deploy to mobile platforms
You should note that iOS support is coming up in June, in the meantime you can develop for Android.
