Narrative:

Taxi from X aviation to Y aviation. Instructed to hold short of active runway. After this instruction was received, the captain told me to switch to clearance delivery and get our clearance. As I was trying to get clearance, I was looked down to write and we crossed the active runway in front of a landing large transport. The pilot may have been thinking ahead too far for the flight by wanting to get the clearance. He should have waited to get clearance at other FBO. Both pilots should be aware of surroundings.
