Tech Erra has discovered several lines of code in the latest iTunes beta that makes it look as though Apple is planning to add app rental capabilities to the App Store. The strings in question read as follows:
"510.036" = "Apps are automatically removed from your iTunes library at the end of the rental period."; "510.037" = "This app will be deleted from your computer."; "510.038" = "These apps will be deleted from your computer."; "510.039" = "App";
App rentals could be one of the items Apple will announce at its big media event on Tuesday.
