Hi all, Before I post the issue, yes I used an internet tethering "hack" as I am on AT&T. I've never used it and I don't plan to unless I can actually afford the extra money. My fathers iMac instantly detects my iPhone 3G when plugging it in via USB and within seconds the internet tethering bar appears. This isn't the case with my (overly outdated) PowerBook G4. I have internet tethering on, and it is set to USB tethering. I have a perfectly fine Apple USB cord, although any apps that are set to discover the 3G (iTunes, iPhoto) never detect that the phone is indeed plugged in. Now, my question is, could this be because of the cord, my outdated computer (which is on 10.5.7), or the phone itself? Thanks in advance.
