This is actually GOOD for most of us. Most of us stay with the carrier long term. The people that jump carriers, get cheap phones, etc jack up prices for us. THey subsidize phones to get us to sign contracts. IF we aren't staying in our contracts they need to find a way to make money again. I'd rather they did this than start raising prices on handsets or plans to compensate.
now, Verizon sees less of this than GSM carriers, because most of Verizon's phones are CDMA only or their world phones are not capable of GSM in the US, so they can't be used very easily after leaving Verizon.
