I was very close to signup up again with the iphone 5, even had an order placed but then checked the speedtests.
My criticism is always constructive. Where it's not constructive is with regards to Sprint's strategy (including previous) and plan. Personally, I really want them to succeed and do well, however, they're still on life support.
As someone who has actually worked on upgrading and building wireless networks abroad, from a practical, engineering, and business perspective, I don't agree with their unlimited stance. They would also win a hell of a lot more customers if they simply included at least 0.5GB in their plans, without the premium fee.
