I am currently on the Canada Wide Double Promo 56 Plan. I have the iPhone 4s on a 150.00 tab (currently at -45.95).I was thinking about getting the iPhone 5 on the new large tab for $200.00. Does anyone know if I can keep the plan I am on now? And also,do I pay off the remaining tab balance or is it added to the new tab for the iPhone 5? I'm only going to upgrade to the 5 if I can stay on the Canada Wide Double Promo 56 plan!!
