I still use my iphone 4. I feel like I really need to upgrade after reading this thread haha
No, you're fine. I was lucky to get a good deal on my used iPhone 5 but if not I would have been very happy to keep using my 4. It has the same quality screen and can do everything the 5 can do except Siri which goes unused by 90% of iPhone users. It was a fantastic investment for anyone who bought one in 2010 ... It's a 3 year old device that while a little slow now is basically still a high end smartphone. Unless you can get a great deal on a newer iphone I say keep it!
