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. Somebody can write to me, how can I use the SiphonSettings on Simulator? For example: setting on the project General / Build / Configuration / Comments (if neccessary setting these property) Regards, Balazs
