How important is it to have unlimited data service? Should this even be a factor in my decision between getting the iPhone on Verizon or AT&T?
It depends on how much data you think you will use. But for the average person, the 2GB plan from AT&T offers plenty of data usage each month. And for some very low-data usage customers, AT&T’s $15 a month plan with 200MB of data is sufficient. And it offers them a way to save some money. But most people will need the 2GB plan, which at $25 a month is only $5 cheaper than Verizon’s current unlimited data plan.
