No, I wouldn't use a much older Apple phone. One of the things I really dislike about Apple is that they don't give clear statements of how long they will provide software updates and in particular security updates for on each product. For a device like a phone that is inherently connecting to external networks all the time, I regard those updates as essential. There also seem to be some vulnerabilities inherent in the design of older iPhones that have been addressed in newer models. Another thing I really dislike about Apple is that iOS Safari lags behind everyone else in the industry when it comes to new features and supporting high performance pages. Regardless of why you believe this is the case, again an older device that either no longer gets updates or is unlikely to get many more is a liability. Finally, while the camera on older iPhones might be half-decent by today's standards, I prefer one that is actually decent.
