title: What options are there for cross-platform (iPhone, Android, Blackberry) development?
body: <p>Me and my friends are starting app development. We have created 2 apps now, and have 3 more in the works. We're looking for a development tool or environment that will allow us to build games that works on all the major handsets. We're using Flash at the moment for cross-platform, but are there any better and more powerful options?</p>
  
  <p>Or would it be best to write the code in one language, then convert it line by line to the others? How do the creators of games like Angry Birds do it?</p>
  
  <p>Thanks.</p>
