iPhone4 usage

So I recently upgraded my 2 year old iphone 4 to a 4s (i had my reasons). The 4 still works, but a good portion of the back plate is missing since i dropped it. It hasn't lost any functionality, but I'm wondering what use I can have for the old 4, whether it's as a remote, media player, etc. Suggestions are welcome.

There are many repair services that can help you with the back plate. Then you can sell it.

If you keep using it without its back plate it will eventually develop other problems, so my advice would be to fix the thing.

Agreed the back glass is a cheap and easy fix.

if it is 2 years old it is a phillips tip and you can get a new back on amazon for around 15 dollars with shipping. It takes only about 1-2 minutes to do. Make sure the mute switch is down when you pull the old one off.

You can get a OEM Back replacement on Amazon.com or other stores live Applepartsstore.com for around $10-15, its a simple fix and most of the companys on there that sell the parts will also include a pentalobe screwdriver when they send out your part.
