I went into a verizon wireless store today to buy 2 cases. they included a screen protector and then gave me 30% off. The lady asked if i wanted the screen protector installed on my phone and i said sure why not, So she took the phone and said im going to go to the back because there is not as much "DUST" in there. and before i knew it she walked rite in the back. She was in the for about 7 mins, and when she came out she didn't have the screen protector on but Yet she was still "CLEANING" the iphone screen for dust. Is there any chance she could or might of installed some spyware or something of that nature? if so , how can i check and see if she did? or check if anything was installed "Behind my back"
