I lost my 4 around the end of July last year at a bar. (dead battery, never appeared on find my iPhone.) It was around the time at the height of the iPhone 5 rumors so I reverted to my original model 8gb while waiting for what eventually became the 4s to come out. It was unbearably slow for about a week, then I just got used to using it again. Sadly the battery life was ungodly low by that time, and the 4s didn't really impress me, so I bought a iPhone 4 32gb off a guy on Craigslist and am back on that now. I still love my original iPhone though. It sits permanently on a cradle in my bathroom and streams pandora for me while I get ready in the mornings.
