The Apple iPad released back in 2010 isn’t compatible with the latest version of many applications. The App Store will now allow this tablet to install older versions of software that it is compatible with.
The original iPad could not be upgraded to iOS 6 when it was released last year, so third-party software that requires this version cannot be installed on that device.
However, reports are coming in that attempts to download incompatible apps result in an offer to download the last version of the software that will run on the older device.
Apple itself has not confirmed this as of yet.
