I have at&t or cigular whatever, it says we have 8000 something minutes that expire april 24. but it also says anytime minutes we only have 731 left. so do i have 8731 or just 731 or just 8000? and it also says we've used none of our rollover minutes. do rollover minutes only start once you've used up all of your regular minutes? are there any catches with rollover minutes?
