I was just wondering when there will be an upgrade to the iphone app so that you don't have to keep the app open for you to hear the alerting sounds. or have I just got the app misconfigured?? Currently running ios 5.0 on a 4S. I would like to be able to lock my iphone and like the email "ding" have the prtg function the same way. As long as my phone is powered on and able to talk to my PRTG server and regardless of what function/state the phone is in, if an alert comes across, the PRTG app will always send out that audible alert.
