Narrative:

Told to expect runway 26 on arrival. Clearance to 2000 ft and turn to the south. Cleared to follow traffic (which was for runway 26) and to contact tower. Captain accidentally hit button to switch #1 communication to #3 and put in 135.15. Called tower and told him it should be 125.35. 135.15 told us cleared to land runway 27 and captain said we should be on 125.35. Tower again said to sidestep and clear to land runway 27. We turned for runway 27 and then I saw traffic to runway 26 turning to final. We never heard or acknowledged a clearance for runway 27.
