Installed iTunes 8 and iPhone 3G no longer shows up in devices

I am having the same problem, can anyone help?

No answer but my iPhone started not showing up in iTunes on my Mac Pro for me yesterday. It works fine with my MBP but not my Mac Pro. I tried different USB ports and a different cable. Sometimes a reboot of the MP and/or iPhone works and sometimes it doesn't. Kind of frustrating. Any ideas as it appears to be software related on the Mac Pro since it works fine on my MBP?

This sounds like Apple Mobile Device Support needs to be restarted and or reinstalled.

I did find that support article yesterday. I skipped the uninstall of iTunes step but did remove the Mobile Device items, rebooted, and then installed iTunes with no change. The reinstall of iTunes did put the Mobile Device items back. I guess I will go through all the steps next time and uninstall iTunes first....didn't want to have to do that but looks like not too many other options. Thanks for the reply.

Well, that didn't work either. I forgot to add that my iPod connects just fine to my Mac Pro so it is only my iPhone on the Mac Pro. Funny thing is I eventaully get it to sync....sometimes a reboot of my phone works while other times a reboot of the Mac works. Other times, I simply hold the top button the iPhone to begin the power down function and something wakes up and it connects to my Mac so I cancel the power off. Very strange how random it seems.

No solution yet but wanted to post additional information. It's very strange how this all of sudden starting happening and how inconsistent the non-connection is. Essentially, when I plug my iPhone to my Mac Pro, no device shows up in iTunes and therefore no sync; however, if I just leave it connected it seems to magically start after so many minutes. Using Activity Monitor, I noticed the AppleMobileDevice (think that is right) service was not starting up upon connecting my iPhone. I just kept AM open and after about 5mins or so, the service started and my iPhone starting its sync. So I think the right definition of my problem is not that my iPhone doesn’t show up in iTunes but that there is a delay before it shows up and that the delay seems will vary. Very strange. I’ll keep testing and report back.

and things continue to get more strange....this time for the good. Starting late last week, my iPhone connects and syncs perfectly every single time now. No idea what happened. This must be an isolated incident that is specific to my configuration. Oh well.

I tried the uninstall and install and it did not work.
