Using iphone first and then connect to itunes?
So I was using my iphone for some time and normally my iPhone would backup through iCloud.
Now that I can't backup anymore because the iCloud storage is full and I don't want to pay money to upgrade it.
So I tried to connect it to my laptop (Macbook Pro) and the only options it gives me is to configure as a new device, or from some old backups from older iPhones wich where somewhere on my laptop.
I have no idea what to do because I want to make a backup of my iPhone on my Macbook Pro. I have an iPhone 6.
iPhone 6, iOS 8.3, null
