Need to force an iOS update Hi my iPhone 3gs is currently operating on 6.1.6.
I'm trying to load an app &amp; when I push install a window comes up telling me I need to update to iOS 7 or later.
My software updates say I'm up to date.... Is there a way to force an update???
The iPhone 3GS is only upgradeable up to iOS 6.1.6, released February 21, 2014. [Wikipedia]
