I plugged my iPhone first into my keyboard, nothing. The battery didn't even charge. Next I plugged it into my iMac, the battery charging icon appeared but nothing else. The iPhone doesn't show up under devices in finder, iTunes (9.2), or iPhoto (8.1). If I go into About This Mac -> More Info -> USB, the iPhone is listed as plugged in. Other than that, I can find no mention that I've plugged it in. Any suggestions? Oh, wait, one more thing. When I launched iPhoto, it said an update to 8.1.2 was available. It then launched Software Update, which told me all my software was up to date. I'm confused, is 9.1.2 available or is it not? And is it related to iPhotos ability to see my iPhone? iPhone is currently running 3.1.3, I was hoping to update to iOS 4.0 right now but obviously can't since iTunes won't even see my iPhone. Edit: On Saturday I replaced the 320 GB hard drive in my iMac with a 1 TB. Prior to the swap I had used Carbon Copy Cloner to ensure the 1 TB would have the exact same files as the 320 GB. Despite this, a few 3rd party extensions in the system library have been complaining about needing to be reinstalled or something... mostly stuff from Ambrosia I think. I don't know if maybe that could be related. Edit 2: I just tried to connect the iPhone to another computer which had it show up in iTunes, Finder, and iPhoto. Its running the same version of iTunes and Mac OS X, although it has iPhoto 8.1.2 rather than 8.1.
