So, if you go to the Pre3 learn more site, it has been a blank page for a few days. I got it to load today and i noticed something different:
1. Within wireless coverage area only. Actual speeds may vary. Email, mobile number, and related information required for setup and activation. Required data services sold separately; unlimited plan recommended and may be required. Not all web content may be available.
All Sprint phone require unlimited plans for the newer phones since the samsung instinct came out. Also to note that Sprint is the only carrier that still has unlimited data.
It might be a clue, might not, but I am pretty sure that changed. You can go look yourself here:
