Apple on Tuesday updated both its Apple Store buying app and (in a "silent" update) Maps application with expanded options. The Apple Store app (free) now features in-store availability checking, and more finely-grained delivery options -- making it possible for customers to choose to have some items delivered and some for pickup, notes AppleInsider. The Maps app, which has already received smaller "invisible" bugfixes since its debut, dramatically expanded its Flyover cities and other features in recent days.
