Should I be suspended for recording a fight in school?

Today there was a fight in my History class. I recorded it on my iPhone. I showed it to a couple of people and then word spread that I had it on my phone and I was called down to the office so that they could look at it. They kept my phone for the rest of the day. I didn't send it to any of my friends nor did I have any involvement in the fight besides recording it.

My principal suspended me for 2 DAYS OUT OF SCHOOL. I think this is very unfair. The reasons she wrote were "Wireless communication device / Any act which disrupts the educational process"

I don't understand what I did that is so wrong here. I recorded a fight, I know that, so I'm willing to be punished for having my phone out in class but 2 days of an out of school suspension?! I think that is completely blown out of the water. The most I should get is a couple of days of in school suspension in my opinion.

My question is: Can i fight this? I don't want this on my permanent record because I want to get into a really good college. I'm a mostly straight A's student, this is my first time actually ever being in trouble in the office. I'm scared for my future.
