Yeah, she's an idiot for not knowing that you can't sync multiple libraries, wait a minute, most of you didn't know that either:D
 
To tell you the truth... there's not a whole lot of information floating around the web that you can't sync the iPhone with more than one computer. Especially if she had an iPod or iPod touch before buying the iPhone. I upgraded to iPhone from iPod touch and I assumed that it worked the same way and I didn't realize it was different until after I bought the iPhone.

You would think it's common sense to think that if the iPod touch can do it, the iPhone can do it too. Afterall, the iPhone is like a super iPod touch with a camera, microphone and cellular data.

I have no idea why they restricted this but it gets on my nerves.

To be honest I've missed the whole iPod Touch craze (had the iPhone 3G first before the iPod Touch) thus what ever I learned with the iPhone I would of tried to apply to the iPod Touch but I'm weird like that.

A quick search though google reveals that one way would be to jailbreak the iPhone and run a nifty app called SwapTunes on the iPhone itself to swap between the 2 libraries. Another way is as I've said to move the media (especially the itunes xml files) to the second computer and thus you can sync the phone between the two (assuming the same iTMS account is used on both). Yet another way as the OP said is to use a hex editor and change the persistent ID on the second library to match the first.

There's tons of ways to sync the iPhone with 2 different computers legitimately but if you're trying to share music with your gf/wife/etc since you bought it once then I can understand the frustration that iTunes and the iPhone would cause.

Still the issue exists that why would a woman thats literate with computers not simply be able to "just google it" and find out a solution to the problem rather then cry and drop it on the floor in frustration. That and the OP for writing a lengthy argument about not letting nannyware and corporations rule your digital life style thus if you have nothing to hide and do no wrong you have nothing to worry about from iTunes or Apple.
 
All this talk about stopping piracy, but why is the iPod able to do all of this (iPod touch even) but the iPhone will not?

What if you're at work or a friend's house after just buying a new CD. You want to copy the CD to your iPhone... well... too bad. You can't. You have to wait until you get home to YOUR computer to put the songs on it.

What is different about the iPhone where they can't make it behave like the iPod where you can copy songs from any iTunes from any computer?

Most likely Apple met with AT&T or some of the companies responsible for producing content for the iPhone/iPod Touch and hammered out a deal based on the inclusion of the cellular data services within the iPhone and either due to patent disputes in how it works or simply shutting out people from sharing music libraries across their friends/families/etc computers they more or less blocked it from doing so. Given the popularity of the iPhone I'm not surprised the restriction exists on it given the data portion and popularity but the fact that you can simply take your iTunes files and copy em to a second machine shows that while not as easy as just plugging in the device that it is possible to do but discourages you from going to someones house and loading up on their music.

Again. The iPhone has been the same since it was released. So even before it was popular, people were blocked from syncing with multiple computer.

Yet again... something the iPod touch has been able to do since day one and every single iPod before it.

Also, why would carriers care about what computer you're loading the music from? This has nothing to do with cellular data. The iPod touch has the same iTunes interface and iTunes Store.
