Should cell phones be allowed in Army Basic Training?

What are you opinions on Trainees being able to have their cell phones is basic training. As a prior recruiter all I can remember is the recruits posting "selfies" and pictures onto our station facebook page. Is it a good thing that the army is getting additional free advertisement, or is it a distraction from training? Coming into the army in 2003 we weren't allowed to have anything like this at the time, and our phone calls were on Sundays only and lasted about 30 seconds which half the time was punching in the numbers on the back of the phone card into the pay phone.
