I've ordered a new iPhone and a new Macbook in the past 48 hours. According my Apple Order Status, my iPhone will arrive tomorrow and my Macbook will probably arrive 3 - 5 days later (after the weekend). Should I WAIT until my new Macbook arrives before I sync-register my new iPhone? I really do NOT have any calendars or contact information to sync to my iPhone (from my existing computer) except maybe a small handful of songs on iTunes. As an FYI, my existing computer (that I would sync it to) is a Mac that I will not be keeping. I do not think I will anyway. If I can sync the iPhone to two Macs (with 2 different Mac operating systems)... maybe I will. Also, along the same topic, my existing iTunes account has been used by me for 3 iPods and 2 re-installations of iTunes on 2 of my computers. I really do not understand the limitations of iTunes yet (re: how many installations and iPods it allows per account). So, I'm curious as to whether I should create a new iTunes account for my iPhone... just in case I'm getting close to any limitations iTunes places on these types of things. Honestly, I have only downloaded about $20 - 25 worth of iTunes songs... so it is not like I'm a heavy iTunes user. Most of my songs are from CDs I already own. Thanks for any counsel on these two related topics!
