I'm not 100% sure, but I don't think ObjectiveC metadata is covered by the Fairplay code encryption. If that is the case, then you can just download the .ipas using iTunes, and then run classdump ( http://stevenygard.com/projects/class-dump/ http://stevenygard.com/projects/class-dump/ ) on them to get a list of ObjC classes. From the class names, you can then figure out which frameworks are linked in the app binary. No jailbreak required :)
