Hi! I successfully compile the siphon on the iphone simulator, but when I try to use it, I get the following message on the simulator device screen: Siphon requires a valid SIP account. To enter this information, select "Settings" from your Home screen, and then tap the "Siphon" entry. But when I try to compile the siphonSettings, I get the following errors: /Siphon2/Settings/Classes/SiphonSettings.h:27:41: error: Preferences/PSListController.h: No such file or directory /Siphon2/Settings/Classes/SiphonSettings.h:30: error: cannot find interface declaration for 'PSListController', superclass of 'CodecSettings' /Siphon2/Settings/Classes/SiphonSettings.h:36: error: cannot find interface declaration for 'PSListController', superclass of 'AdvancedSettings' /Siphon2/Settings/Classes/SiphonSettings.h:42: error: cannot find interface declaration for 'PSListController', superclass of 'PhoneSettings' /Siphon2/Settings/Classes/SiphonSettings.h:50: error: cannot find interface declaration for 'PSListController', superclass of 'NetworkSettings' /Siphon2/Settings/Classes/SiphonSettings.h:57: error: cannot find interface declaration for 'PSListController', superclass of 'SiphonSettings' If somebody know the solution, please write to me.
