I understand you add a line to your family plan with the cheapest data package. Receive the phone, activate it, and then go to the store to switch it to your main line. You then add a dummy on the new line and cancel the data plan. My question... When the 4s came out, our unlimited data packages changed name and capabilities. It when from 'Unlimited Iphone Data' to 'Unlimited Iphone 4s Data'. ATT also change the name and capabilities for the IP5 to 'Unlimited Iphone 5 with LTE'. Do you guys anticipate any problems for use guys taking advantage of the new line loop hole ? Did anyone who did it for the 4s have their data lines remain the same or change ? I'm assuming it at least doesn't compromise the unlimited data portion. Thanks guys !
