Anyone here still using their iphone 4?

Since the iphone 6 is out… I've seen less and less people using the iphone 4… I don't see anything wrong with it but is it weird to still be using one? I go to a private school so when I had to take the regents, everyone was supposed to hand in their phones and I discovered that I was the only one in the room with an iphone 4… Is it because it was a private school? I know this is a bit silly but… I'm probably going to upgrade when the newest iphone comes out in September…

Doesn't really matter at the end of the day. You have an older phone. That's all.
