Erase All Content and Settings when swapping iphones.
My husband and I are going to be swapping iPhones when we get the new iphone 5S. I remember how to do this on our own by swapping sims and then calling AT&T to correct the IMEI numbers. I have forgotton however, when doing the erase all content and settings, do I do this before or after I remove the sim card on each phone?
THANK YOU!
