I just got the 5s and had a 4 beforehand, i'm waiting for a call on my old phone to have my sim and number transferred to the new phone - in the mean time can i do the restore old backup from my iphone 4 to the 5s or do i have to wait until i get the sim up and running?
also is it ok to backup? I've read mixed replies - some saying that because its a new phone set it up as a new device don't backup. Some say its ok. I don't want to lose any of my messages, pics etc
