Flex 4.5 build for ios

HI,

Right at the beginning of my flex journey and so I'm using examples to see how stuff is done.

I have done the recent adobe flash builder update and can make simple flex builds for ios, google android and blackberry. Cool.

I have sourced a demo flex 4.5 project that was done for android (I think before the update) but when I go to do a build for ios

the option on the drop down is not there (just has google, no ios or blackberry) So I guess the project thinks its in pre-update mode

So the question is, what is causing the drop down to only have google, is there some library/framework/script I need to add or something

so this demo flex project that was writen for android can be tested on ios.

hope this makes sense!

thanks

mike
