Can you use a deregistered iPhone?

Basically, since I plan to sell my iPhone, I want to unregister it. Will I still be able to use it like that? What will that do exactly? Will that take my apple ID out of the device and delete my email and iTunes info, etc.?

Yes, it will. Why not keep it registered until it is sold?

That's what I was asking, I had no idea. I wanted to get the info before I just went ahead and did it. Thanks!
