You are allowed 2 personal items in your room during your first year (4th degree year). These can be anything you want to bring from home, subject to some rules. Our son took a digital picture frame as one of his personal items. Some things like sports equipment are exempt from the total, but it depends on the squadron leader's interpretation. Our son was allowed his powerlifting equipment (squat suit, deadlift suit, bench press shirt, belt and knee wraps) to count as one item.
Laptops are provided by the Air Force, but you do pay for them. The cost of the computer and your uniforms is deducted from your cadet pay each month.
This year, cell phones were given back to the 4 degrees after Parent's Weekend (Labor Day), but only on weekends. Every year can be different, there are no guarantees. Also, some squadrons took the cell phones back, even on weekends because of infractions. You can be subject to this even if you personally did nothing wrong, but someone in your squadron did.
No iPods, or any music, are allowed until after Recognition, sometime in the Spring. Cameras are allowed right away, and do not count towards your personal item total.
Soylent was accurate his advice, except that iPods are not really 'given back' after Recognnition. That is when you can have your parents send them out to you. In other words, don't bring them with you to the Academy if they are not allowed.
Very good question, by the way.
