So I'm thinking of buying a second-hand iPhone 4 (or 4s if it's a reasonable price.)
I suppose the main question is has anybody here done the same? Have you had any problems with doing so? I've never bought anything this 'big' second-hand before (for the same reason that I can't buy it new, not rolling in the money!)
And whilst I'm on the subject, am I the only one that can't understand people who flocked to get the iPhone 5 after only having their 4s for a few months?
