Narrative:

Landed runway 31R. Instructed to hold short of runway 35C, then instructed to expedite across runways 35C and 35L. I read back instructions. Tower then repeated clearance. I noticed that I was on communication #2, switched to communication #1. At that time, tower canceled crossing instructions. Since captain heard me read back the original clearance to cross, he began to move across the hold short line. After tower issued the newest hold short instructions, I told them we had already crossed the hold short line. Tower at this time had aircraft Y on final go around.
