As a SERO customer, I am very happy they are doing this. The only thing I dont like (and this goes for all plans, not just SERO) is the extra $10 fee for having a 4G phone (AKA EVO Coolness tax).
With that being said, if I were to get a 4G device, i still only end up paying $50 per month with is still cheap as hell
I can't wait till October.
