I've had my Droid 1 for too long now and now that my contract is up, I'm planning on getting the Droid 4 today/sometime soon. I have cyanogen on my droid 1 however, and I know that if I sent it out for warranty/repairs/etc I should unroot it, but what if I'm buying a new phone? If I recall correctly they do need your old phone to transfer the number over or something? It's been a while so I'm not sure. Should I unroot before heading over to verizon? Thanks.
