I bought an iPhone 4S using an upgrade swap. I upgraded Line 2's iPhone 3G (off contract) to use the 4S on Line 1 (which was an iPhone 4). Then we added a line from T-Moblie to create Line 3, now using Line 1's old iPhone 4. So our account looks like so: Line 1: iPhone 4S on contract until Feb 2012. Line 2: iPhone 3G on contract until 2013 Line 3: iPhone 4 on contract until 2013. My question is, why is it that I got the contract on the third line? I essentially supplied my own equipment. I only bought one phone (the 4S) and they gave me two contracts. I went into the store and they said since I had a FAN (through the military) discount that the contract would automatically be added. There was no way around this. They said that since I provided my own equipment they would add a note to my account to let me upgrade or cancel my service at any point. But my account would still say I had the contract. Are they just saying this to lock me into another contract on the third line?
