B737 flight crew experiences split flaps during a visual approach and elects to go around. During the go around the flaps are retracted without regard for the split flap condition. A flap over speed also occurs. The aircraft is configured using the QRH and a flap 15 landing ensues.

Narrative:
On final approach we were configuring aircraft for a flaps 30 visual approach. After moving flap position from 15 to 30; we had a split flap occurrence. One flap stayed at 15 and the other stayed at 25 with the flap handle at 30. We elected to go around and while doing that; the captain called for standard missed approach procedures. We cleaned up the aircraft to a clean configuration and then went through the QRH for a split flap occurrence. We should have kept the aircraft dirty or at least moved the flaps to 15 and then gone through the QRH. However; this is not a memory procedure. The go-around was very busy coordinating with my captain (pilot flying); our jump seat pilot; and air traffic control all the while having to maintain separation from a B757 (wake turbulence) on departure. We reconfigured the aircraft via the QRH procedure; and came back for an uneventful flaps 15 landing.
