Save for my Nokia 3310 that I had when I was 16 whose case I changed into a Tigger case, I've never quite bothered with phone covers until I got my iPhone. My phone has seen several cases, including a batshit crazy-heavy one I got done in Bangkok:
Late last year, I got a Casetagram made, and I haven't changed it, or gotten sick of it since. It's perfect. There are photos of my my family, my Love and some of my favourite things. It's nice to flip over a phone and get reminded of the best things in life.
What does your phone cover look like?
