Since the iPhone was first released, early adopters haven't stopped talking about what they think of the device. While the free promotion can be a great marketing tool for wireless carriers, it can be crippling if users have issues with session and network quality. Verizon's Voyager and Nokia's N810 must isolate and prioritize network problems to ensure that customer issues are addressed as quickly as possible. Ensuring that these early adopters have a positive experience is essential for having any chance at the viral adoption the iPhone experienced, along with a low customer churn rate.
