I've got the plan with 450 minuted ($69.99/mo) + unlimited texting ($20.00/mo). My nights start at 7 PM. My bill has been $163 for like the past couple of months. For those of you with a similar plan, how much is your bill after taxes, surcharges, etc.? Also, if I decide to get another phone from AT&T, will I have to pay to cancel my iPhone plan and then sign a new contract? How does that work?
