This is Raju from the InMobi team here. I just had a quick look at your app integrations. All you would need to do is to complete your App verification process. This would ensure the activation of your app on our network and you would start to receive ads.
Do write in to helpdesk@inmobi.com in case you continue to face issues.
Also, the InMobi diagnostics tool is a nifty way to identify issues around your integration. You could read more here: http://www.inmobi.com/helpcenter/publisher-help/integration/how-to-set-up-publisher-diagnostics/
Hope this helps.
