I tried to stick with a 5s, but after having two, I just didn't really ever like it. My first iPhone however, it was the 5c. That device is still my favorite ever. If it wasn't for the fact that the 6 has extra bands that help me get signal in places I didn't use to (T-Mobile), I'd still be with my 5c. I'm hoping and wishing on pipe dreams that there will be a 6c.
An iPhone 6 in a cheap plastic case? Yeah, just gotta have
