Nope, it will force Sprint to do without unlimited data plans, just like the others have done in the past. Everyone started claiming the phone will be better on their network, only to realize that their network was not able to keep up with the technology (be it Android or Apple). Thing is, history repeats itself, it's only news for people who do not learn from it.
Another thing is, nowadays everyone is pushing for more bandwidth usage, via cloud features and what not. At the same time, bandwidth providers are tightening the screws on their services, charging more for (more) limited bandwidth. It's like they're ignoring the trend, and that's why one can find awesome deals in other countries that offer true competition in this field.
Until the telcom monopolies are broken, the customer will continue to get the bad deals here.
