If your iPhone happens to be running on AT&T's cellular network you might be staring down the barrel of a price hike starting next month, the company has warned.
The carrier has announced details that will affect customers of the now defunct AT&T unlimited plans which some people have remained grandfathered into for some time now. A number of plans will be impacted with AT&T saying that customers with a single line will see their bills rise by $10 each month.
