Will iphone 4s still work de-activated?

Right now i have the iphone 4s with verizon but i'm getting the new iphone 5. Once i deactivate the 4s will it still work for like apps. Because i have alot of music in it. Or will it just shut off

You could easily use it for iPod. When you're connected to Wi-Fi, all of the apps will work. It would be no different than putting your iPhone in airplane mode. You just won't be able to make calls.

It will still work except for calls and txts aside from the apps that allow you to do that. You said you have a lot of music on it… Just curious, does that mean you no longer have access to that music to put on your new iPhone? If so I just wanted to let you know that there are third party apps that you can download onto your computer to pull the music from your phone and copy onto your computer.
