...pin/password code? My eldest son likes to play around with my phone, ie, listening to music and playing games, i have no problem with this but he tends to change my wallpaper/screen saver/ring tone/caller id photos/ message tones etc etc....on a regular basis....grrr!!!.. on one of my last phones, a Samsung D900, unless you were making or receiving a call, or looking in the address book, you could'nt open or look at any other of the features unless you entered a pin/password code ( which i enabled, some how...lol. ) each time. Try as i might, i cannot find this feature, or find how to do this on my 3month old Satio.........HELP!!!!!! I now have no hair left to pull out!!
