Should I wear my FBI badge to dress as Agent Scully for Halloween?

I accidentally submitted this with no details (blame the iPhone). Now, the FBI badge has a picture of Gillian Anderson on it and does not look like me. However, it does have FBI in big blue letters on it. It goes with the costume, but an old dude at my bus stop kept nagging me saying I shouldn't be walking around NYC dressed as a police officer because it's against the law. I just don't know if I should only wear it around my college campus or not at all, or whatever… Any input appreciated

Does VPN protect iPhone applications?

I have recently gotten into all this "technology" and everything else. I wanted to have more security when it came to my iPhone applications so I was wondering… Does VPN secure the internet connection as well as the applications I'm using? (such as Whatsapp, Viber, etc.).

Understanding how a phone bill works?

So for Christmas, I plan to accumulate money and buy the latest iPhone or at least one of the latest models. My family is currently using Verizon and running all non apple phones. I'm curious to what a phone bill actually pays for. Like, if I were to pay the phone in full, would I have to pay monthly? And I've heard that apple bills are more expensive? Is that just because the phone costs more and that is the price broken up between months? Also does the phone bill change depending on how many phones are on the plan?

Upgrading your phone saves you money? Verizon?

I recently got into an argument with my s/o about upgrading her phone. She claims that the people working at Verizon told her that upgrading to the iPhone 7 would be cheaper than keeping her iPhone 6. She claims they said that once she finished paying off her iPhone 6 the monthly service fee on her phone would rise over the monthly payment she makes on her phone.

So for example (Numbers are not actual representation.)

She pays $100 a month. $25 is the month service for her phone. $25 is the payment for her phone. $50 is payment for data minutes and texting.

Verizon told her that when she is finished paying off her phone (iPhone 6) The monthly service ($25) would increase to over $50. Meaning that by paying off her phone she would increase her monthly charges to over $100.

Can anyone make sense of this?
