I noticed today that AT&T is offering unlimited calling to ANY mobile phone (any carrier) for free if you have the unlimited texting plan. I think you have to have at least the 700 minute plan (for family) to qualify. Maybe their trying to save some customers from going to Verizon now that they offer the IPhone. I've been considering losing my home phone for a while now. At least this will make it a little easier to do that.
