iPhone 3.0 and iTunes error -4

Like many iPhone users, I just downloaded the iPhone 3.0 software and installed it onto my phone. The download and installation went fine, but when I plugged my phone back into my computer I received this error:

Furthermore, my iPhone wasn’t being recognized by iTunes. Coincidentally, this happened to me right after a friend on Twitter was complaining about the issue.

Here’s a solution I found to get iTunes to recognize your iPhone again:

  1. Quit iTunes
  2. navigate to System/Library/Extensions and delete AppleMobileDevice.kext (you may be prompted to enter your admin information)
  3. Restart iTunes

Pretty simple, but here’s the official word from Apple Support, in case you want it.
