No wonder there are so many network related complaints......
I look at this from another perspective. You know how there are so many reception related complaints with the iPhone and at&t's 3G network? That's partly due to ex Verizon customers who were 'used to," a much more reliable/stable network to begin with.
When you go from something better to something sub par, you are much more likely to vent as opposed to the other way around.
