Technology is great overall
I've only had a cdma phone once, and there are still a lot of things I don't understand about it personally, but it's good they are coming up with more options for cdma users.
It was a paygo phone, I lost it, and just stopped topping it up. I don't know if it ended up being much use to someone. They couldn't put a sim in it, but I guess they could have activated on their own account.
