> you can go dig up your old iPhone out of the closetYeah, but the point is, I don't have to do that with old DOS programs. I get an emulator, whip out my old binaries, and it runs on my shiny new PC.
On iOS, strictly speaking, there is no such option -- you will have to go to a non-iOS device to run an emulator - and this assuming either Apple is still hosting iOS5 apps (which probably won't be the case for long), or I have some backup (again on non-iOS) that I can somehow leverage.
It would be very kind of Our Betters At Apple to allow some sort of iOS-on-iOS emulator, if they're at all serious with the "iPad for work" concept. Companies already struggle with Microsoft upgrade policies that are much more conservative...
