I just stopped in at the Verizon store with the intention of trading in my 4 for a 6. Also, since we have an old voice plan from back in the 2G/2.5G days, I was under the impression (from a previous visit to Verizon) that a new data/voice/text plan would make a pleasant drop in my monthly bill. Uhh, no.
So, for the time being, I'm keeping my old phone and my existing plan, where I'm already out of contract and my wife will be too in 8-9 months. Verizon just cost Apple a sale.
