Yes. IPhone 4's don't even get updates anymore and your phone is more open to viruses. Yes, iPhones can get viruses. If you can't afford an 5S, go for a 4S. It still gets update until iOS 10, but I'd go for a 5S. And don't go for a 5C. pieces of **** and don't even get Adblock or the new night mode

colors and cheap are the two selling points, that's it.
