Is searching through someone's mobile phone without permission illegal?
In some cases, it may theoretically violate the Digital Millenium Copyright act in the U.S, and may also fall under relevant corporate espionage statutes in other places.
However, for the most part it is unlikely that any prosecutor will be interested in a case where one private citizen snoops through the phone of another. Perhaps the best answer is "Sometimes it's illegal, but not enough to really matter".

In 1974 Dr. Martin Cooper is given credit for the cell phone that is most like the ones we have today. He was working for Motorola at the time. The phone was only for government use and in 1984 it was sold to the public for the first time. The early cell phones were large, heavy, and copied land line phones in style. They were carried in a zippered bag with the whole bottom as the battery.
The cell phone was first thought of in the 1920's when the use of police radios began. In 1947 Bell Labs made the first cell phone, but it took Dr. Cooper of Motorola to make a cell phone in 1974 for the government. The public use of cell phones began in 1984.

== == * Yes. If she is hiding something, then she is cheating on you in some form. She may not be sleeping with him, but it is still emotional cheating to be hiding. She is giving him her time and attention which belong to you. Get counseling if this marriage is worth saving. == == * Communication with your wife is the key. Considering you are married don't you think it wise to ask her about it. Unless you know for a fact this is her girlfriend's phone # then there is no reason to be suspicious (women talk a lot to each other.) My husband certainly doesn't know all my girlfriend's phone #'s. There is a possibility she may be cheating, but don't accuse her of anything, but ask her if she's unhappy in your marriage because you get a feeling she isn't being truthful to you. Get talking before you second-guess and get yourself into big trouble!
What are some good icebreakers for shy girls?
I'm assuming you're talking to a guy that you like. This is what I used to do: I'd just pretend that he was my guy cousin. I know it sounds stupid, but it really works! I just pretended I was talking to this cousin of mine, then suddenly I didn't feel that shy. After a little while I'd kind of remember that I wasn't talking to him, but it was fine because I wan't shy anymore! After a little while I didn't even have to use this little trick, but it really works.
If that doesn't work for you (it did for me, but hey, we're all different), I'd drag out some old things that work and have been repeated again and again. If you're in the same class or share teachers, talk about that, or mutual friends. If you don't know him that well, try asking him about his favourite football team, siblings etc. Don't let him do all the talking, but neither should you!
I'm not sure if that's exactly an icebreaker, but I hope it helps.
