Load SWF from remote server with ActionScript in AIR iOS. is possible now? (in last version adobe air?)

hi, everyone. greetings from Turkey..

we will write child games for android and ios with adobe air platform.

in android, there is no problem.

but, for ios, we have a few questions.

1) is it possible to download remote swf to ios local and run from local swf in adobe air ios? (games must be work in offline.. but, if there is any update, download updated swf first.. ) if its possible, is there any worked last tutorial for this subject?

2) is there any file size limit for single file like android in ios? (50 mb)

3) when we writes with adobe air 20 sdk, which devices and ios version is supported? for ex. games going to work in ipad 2 or any ios 7 devices?

best regards,

Ercan
