“Back in June at the WWDC keynote, Apple SVP of iPhone software Scott Forstall took the stage to discuss Apple’s answer to the lack of background applications on the iPhone. Many developers had expressed concern about the limitation which could restrict the usefulness of certain applications, such as instant messenger clients,” Dan Moren reports for Macworld.
“Forstall presented a different solution to the problem. Apple would instead roll out a push notification system that apps could use to alert users when remote content had changed,” Moren reports.
“Apple said that it would be available as of September…. [But] the ninth month has come and gone with no sign of the feature, despite Apple shipping a major iPhone OS update during the same period,” Moren reports.
