Technically, you’re already a cyborg. If you keep your cell phone with you most of the time, especially if the earpiece is in place, I think we can call that arrangement an exobrain. Don’t protest that your cellphone isn’t part of your body just because you can leave it in your other pants. If a cyborg can remove its digital eye and leave it on a shelf as a surveillance device, and I think we all agree that it can, then your cellphone qualifies as part of your body. In fact, one of the benefits of being a cyborg is that you can remove and upgrade parts easily. So don’t give me that “It’s not attached to me” argument. You’re already a cyborg. Deal with it.
