When I bought my iBook, I initally had trouble connecting to the internet (via airport) and had to call apple and have them help me set it up. They took me through a series of changes that I can't remember on my own. First, I had to create a 'location' and then alter all of that to make it be able to connect to my router. So, my question is - Can I save the whole 'location' file in case I need to re-install the OS or I buy a new hard drive for my computer so I don't have to call apple and go through all that again? If so, where do I put the file back into to make it a useable location again? Thanks.
