When you boarded, were people in both 3A and 3B? Most common reason for these gate changes is because people want to sit next to each other and gate agents (rightly or wrongly) make some assumptions about seat equivalence. This doesn't always work out (I got extremely annoyed last week when I got moved from 33C to 28D on a 739 to allow a family booked in E to sit in the same row - which means rather than using my touchpad and having my elbow go into the aisle it goes into someones side).
This is very different from Delta's incredibly annoying habit to change planes and - sometimes - just screw up seats for no reason weeks/months in advance (sometimes due to equipment changes but others for seemingly no reason at all).
