I built the S60 example IsvTelCallApp and signed it using my devcert (which I got after requesting all capabilities). When the .sis tries to install on my phone a Nokia E61 , I get an error "Required Application Access Not Granted". I was running the application as early as two days back on my phone. Can someone help me understand what I might be doing wrong? The application is using "NetworkServices, ReadDeviceData, WriteDeviceData, ReadUserData and WriteUserData". I even generated a new devcert and made sure that these capabilities are selected.
