The first time I installed Installer I could upgrade it on my iPhone. But after a restore and installing it all over again, I can't upgrade Installer and the Network apps can't be uninstalled. I can uninstall games and so, but not f.ex. OpenSSH. If I try I get a warning which tells me: "Error executing transcription" or something like that. Can this problem be caused because I installed SSH from iNdependence after installing OpenSSH from Installer? I can't connect to my iPhone using the IP address either...

Enter to your routers configuration (DHCP) and change the IP address. It happened to me, but when I changed it, the connection between mi iPhone and my mac worked again.
