One of my coworkers has it and is happy with it. He gets the new phone, passes down his phone to his wife, she passes her phone down to the daughter. Everybody gets a relatively new phone, only one account has the extra payment.
So the following is not true?
The downside to next is that you have to give them back the phone when you upgrade again. So, you're out the value of the old phone at that time... do some googling, if you're on the old ATT plan you're probably better off staying with that.
Everytime I go in one of the reps tries to get me to switch, and tries to explain they're saving me money. I've run the numbers, (they're not)
Think of if this way, they wouldn't want you to change plans so bad if they were going to lose money by having you switch....
