"Delete all contents and settings" affecting linked phone through icloud?
I bought a second hand iPhone 5, and used the "erase all contents and settings" feature in settings to restore the phone to factory conditions.
The person that I bought it from has an iPhone 6 and contacted me to say that me doing this has had an effect on her phone (with the Find my iPhone app affected.) Is it possible that me doing a factory reset on the iPhone 5 has deleted data on the iPhone 6?
Thanks
iPhone 5
