Is there any word on when Junos Pulse for iPhone will be available in the Australian App Store?
See https://forums.pulsesecure.net/topic/pulse-connect-secure/42951-apple-ipad-and-iphone-support - Apple controls the release schedule.
And Apple sends absolutely no communication to Juniper on the progress of the app approval?
Check the tech press for coverage of the App Store approvals process - it's enlightening
Keeping developers apprised on the status would be a logistical nightmare considering the volume they deal with. And considering that it's one of the first 'persistent' apps it is likely getting additional QA and scrutiny.
