Possibly you picked up a cruise ship that offered "onboard" cell service. If you had something set for automatic data (like using exchange push or activesync email updates) it might have made a data connection. Watch out for a BIG charge from a cruise service for data access. Not sure why the other Sprint servers would not have supplied the same info but it might be a difference in what the mini-cell was offering (on the tower side).
