You can. I took my phone with me, but it may be difficult. You use one hand to "steer" to keep yourself pointed forward, and not spinning circles. You use your other hand as a break, pulling down on the steel cable to break. Not to mention the rig rigging your strapped into fits snug on your pelvis area, and would make it difficult to get a phone into and out of your pocket quickly. We used a helmet mounted go pro we brought with us.
You can take with you...at your own responsibility though. I wish i did actually. They do take pics of your last zipline. At a price of $39.99
No but they take great photos of you and your group on the final run. They even let you but a thumb drive of all the pictures for a very reasonable fee. The pictures of our group were very good quality.
