Hey all, just got an iPhone 4 - yeah! Have an older iMac and iPod. Just went to transfer some tunes off my iMac to my iPhone and need an iTunes update (9.0.2 to 10.3.1) to do so. But I also need a Mac OS X update from 10.4.11 to 10.5 to update iTunes I guess. Can I update for free or must I buy a new Mac OS X? If so, what do you recommend keeping cost in mind? Kind if behind the times as I'm a busy mom of 2 little ones. Any help is much appreciated. Thanks!
