Server Farming With Your Old iPhone
It's always a quandary when it comes to outdated technology. Do you keep using it till it falls apart? Do you recycle it, wait till it comes back in style?
Another option is to repurpose the gadget in question, giving it a new life as something else. An application for the iPhone, named Serversman, can do just that with any spare phones you may have lying around.
This interesting app transforms iPhones into a mini web server, network storage facility, or file viewer. It's downloadable here. and watch the video below for a demonstration.
