Can iPhone applications compiled against 2.1 be successfully installed via iTunes on a 2.0 device?
I know iPhone applications compiled with 2.1 can run on a 2.0 device (assuming they’re not using anything new from 2.1). But am not sure if iTunes will let the install take place.
Does anyone have concrete information on this?
I have not seen any apps on the AppStore that are 2.1+ only.
I believe apps that are compiled against 2.1 will be marked as ‘Requires iPhone 2.1 Softwar Update’ when viewed through iTunes. (but not when viewed from an iPhone – the iPhone’s App Store app only displays a subset of an app’s metadata.)
One example: Caliper (it’s under ‘Application Description->Requirements’)
I don’t know if this ‘requirement’ is actually enforced, however.
