Still on the iPhone 4! It’s slow, but still works and only need a recharge every 24 hours with normal use (last longer if used only as a phone/texting device). What can I say… the longer I’ve kept it the more pointless it seems to waste money (and the environment) on a new phone. My goal is to keep it going until the iPhone 7 is here. By then I suspect the number of apps that don’t support iOS7 anymore will be the end of it.
