Sorry for the stupid question: So I have an iPod and have been buying all my music from iTunes store straight OTA to the iPod, and never actually use iTunes on the mac or plug my iPod into the computer. Im planning on buying an iPhone 4 this weekend, and was wondering if I connect up my new iPhone to iTunes OTA will the phone know to redownload all my purchased songs onto the phone in some way shape or form? Or do I have to plug my iPod into my computer, get the songs off the iPod and then get them onto the iPhone manually? Thanks!!
