Edit iTunes Library.itl file on a mac?

I recently purchased a new Macbook Air and would like to be able to sync it with my iPhone without the loss of data that's currently in the phone. I've done some research and found: "http://www.iclarified.com/entry/index.p… To be a common solution for this issue. However I can't complete step 8 because Hex edit tells me that it's read-only.

Is there a way around this?

P.S. I think it's really bad planning/engineering on Apple's part for this one-computer-to-one-iphone rule. I understand that this could be a measure to restrict sharing of purchases and etc. But if they could have thought of a way for people to verify that it's the same primary user and that the primary user is not trying to infringe against any copyrights, then that should be sufficient enough to allow people to sync to new computers.

For the amount of effort I've put into trying to get my iPhone to "pair" with this Macbook Air, almost makes me regret purchasing it.

Plenty of options at the links below.

The sync isn't to a computer. It is to a phone or to an iPod.

About your URL: Don't add " or ( or anything to it. That cuts it off. You need a space and then http://whatwhat.com and another space, not even a period at the end.

Can you just use your computer to download songs instead of the phone? That would solve the whole issue.
