There are few posibilities that can happen to your hp or
you . First you may be charged if your officer cb enough , 2nd they
may confiscate your hp then there goes your iphone4 , 3rd and most
minor consequence , they will paste a mindef sticker onto your
camera lens covering it so that you can't take any pictures with
the sticker covering the lens .
I've seen mindef phones with the camera covered with the
sticker when i was in nokia care center . And once the sticker is
on your lens , whatever pic you take using the camera will be
blurred even if you remove the sticker . Unless you really spent
effort to clean the lens after you peel the sticker off . Why make
your hp subject to such things ? Bring a normal hp without camera
to camp so difficult meh ?
I had a colleague whom was a civilian technician
working inside one of the airbase , was caught with a camera phone
, he immediately had his hp confiscated and clearance revoked . If
you still want to take chances with your iphone4 , go ahead .
