You Can Buy AppleCare Later
You might be tempted to buy AppleCare with your new iPhone. A lot of you should, but only if you've done your research.
If you're unfamiliar with AppleCare, it's Apple’s extended warranty service. Many of you will eventually want to get it, but you don't have to make that decision during the pre-order process.
If you don't have time to research AppleCare before you pre-order, you'll want to put in the time after you buy your device.
If you aren't familiar with the service and its benefits, hold off until you've been able to weigh the pros and cons.
You have a pretty large window in which to buy AppleCare which means you'll be able to buy your phone and snag the service later if you decide you want it.
