If you buy through a BGR link ... a number of kits are now available that let you transform your old iPhone 5s into an “iPhone 7 mini.” It’s actually not as complicated as you might think ...
The iPhone 5s is sold only in 16GB and 32GB storage capacities, the former very small. If you’re going to buy this model, we’d strongly advise spending the extra $50 for the 32GB model.
