If you can, buy a second cheaper phone for army usage.Security
reasons aside, do you want your new, flashy A1000, 6680 etc to get
banged up and bruised on exercise?
Well, if you are involved in staff work, it might be different.But
try not to use camera phones in camp, and if you want to sneak them
in, do so at your own risk and make sure you don't get
caught.
Oh well.Sometimes you might be able to get an LOA, but don't pin
your hopes too high..S3s/S2s won't normally give grunts any LOA for
a camera phone.
