Is FB 4.5 only for android?
there's like no option for BlackBerry, Windows 7, or iPhone...
Blackberry had press releases with adobe, a while back but their newest phone the BlackBerry torch doesn't even support flash and it's been atleast 6 months.
Couldn't find anything on Windows 7 about flash or air 2.5 support currently or in the future.
iPhone is a weird one, they let other tools to develop apps FINALLY, but flash doesn't run on iPhone or iPad etc...etc...
The preview release of Flash Builder Burrito from late last year supports Android development. We've announced that Flash Builder will support iOS and BlackBerry Tablet OS development as well--we'll make an announcement when we have specific dates to share.
So From your post, I'm reading...
Yes to Android
Yes to iPHONE / iPAD
Yes to blackberry tablet but NO blackberry phone?
No to windows 7 phone.
