Will a backup of an old phone affect my new phone?
I got a new iPhone a month and now I want to erase / restore to factory my old iPhone before selling or giving it away. I'm reading the instructions from Apple on how to erase my phone, but it tells you to back it up before logging out of iCloud. If I backup my old phone (that I haven't used for over a month) will it overwrite the iCloud content on my new phone?
iCloud has burned me in the past. Nervous about backing up an old phone.
