Neither my hubby nor I have anything to hide and know each other's lock PW. Though I can't think of a reason I really need to get into it except to call someone because my phone is acting up again. ;-)
Now, if and when it comes time for an offspring of mine to have a mobile? If it lives under my roof I had better be able to go through the bloody thing if I want to. Not that it'll have a smart phone, or whatever is "the thing" when it's a tween or teen until it can properly afford said smart phone and said smart phone bill.
I did once, but I didnt like myself much afterwards. When I was done I was all like "shit. I'm either one of those people that cant trust/be trusted , really insecure, a nosey twat, or all of the above".
I went through my ex's phone once. I felt really bad for invading her privacy, up until i found the half-naked pictures she was sending to some dude. Then I only felt a little bade.
