My original contract iphone (4s 8gb) filled up within the first year of my 2yr Vodafone contract. I purchased a used 4s 64gb off eBay to see me through the 2nd year. My contract ended 3wks ago, the used 4s/64gb phone I had purchased to see me through was working fine so I decided to get sim only contract. Typically the lock button stopped working today. I'm away for a couple of weeks so will try to hunt down another iphone on my return (5s or 5SE 64gb) in the meantime can I get my original 4s 8gb back out of its box and delete ALL photos ? They are all duplicated on the 4s 64gb plus on iCloud too. Just wanted to double check that by deleting off my 4s8gb will not also delete from 4s64gb or iCloud. Sorry, I'm not very tech savvy.
