When I connect my iPhone to my Mac it pulls iPhoto and iPhoto recognizes my iPhone, but iTunes doesn't see the iPhone at all. I can't even start to activate my iPhone, because iTunes (version 7.3) doesn't recognize it. Anyone else having this problem??? Update: I tried my iPhone on a PC running Windows XP SP2 with iTunes 7.3 and I get nothing!!! SOLUTION iTUNES not recognizing iPhone, couldn't activate After going to Apples troubleshooting page and doing all resets, reinstalls, and double checks, I called tech support. I am running XP Home SR 2 and the updated iTunes. Long story short, I had to go into My computer, manage, services and applications, then services, then click to drop down services. I found iPhone Mobile device service listed. Mine was showing nothing in the status window. I doubled clicked the iPhone Mobile device and opened it to see the service had been stopped. I restarted it and it remained running. I then opened iTunes and it recognized the iPhone right away. I registered in less than 3 minutes and am up and running. Good luck.
