I am considering trading in my rooted evo for the 3d for 150 dollars will sprint give me the trade in or do I have to unroot. I have had problems selling on ebay in the past.
You should unroot the device as a precaution. If they see it is rooted it may not be accepted, even though it's still perfectly fine to use. Since will be trading it just unroot and be done with it. Also, does Sprint give you a trade in value, or is it Radio Shack?
