Iphone 4 unlocking locked to orange

I'm having a very rough time getting my iphone 4 unlocked i can't do it with the original carrier due to me not being the original owner plus i have no contact with them.
So i found this website:
http://networkunlock.org/iphone4/
Just wanted to know if it worked for anyone also i realised they have a survey which asks for personal info. Do they contact you or bug you in anyway after submitting your info? If there are better sites out there that factory unlock the phone please feel free to suggest them keeping in mind they don't charge 80-90 quid for some i have seen.

How did they find me from my mobile number?

So my friend and i were messing around and there was this guy who had been quite rude to her, and i got his number (he 100% did not have my number).
I texted him and he replied saying "who is this?". I didn't reply and then like 15 mins later, he replied with a photo of me! (one of my old fb profile pics)
I have no idea how he got that from my number. My phone is an iphone and i believe his is aswell, but i still don't understand.

Iphone stuck in headphones mode?

I've tried all the ways they suggest online. I've unplugged and plugged my headphones in 20 times, blew air in the headphone jack and sucked air out, put my hair dryer on warm to the headphones jack, reset my iphone, and took a keyboard cleaner air thing to the headphones jack. Any other suggestions on what to do?

Wet iphone problems, what to do?

I just dropped my Iphone into ocean water and I immediately placed in rice. I know I shouldnt turn it on but I did. It turns on but I can't touch the screen at all. Does this mean my phone is broken forever or is there a way to still save it.

also I know I shouldnt turn it on but is there a way to force close it. Seeing that I can't close it by using the screen

Is there any point of getting the 4s?

As a late present for christmas i'm getting my brothers old phone (the 4s) my parents are paying him £100 for it. I don't want to sound ungrateful but i was really getting my hopes up for a 5. With the 100 from my parents hes going to get the 5s.

We aren't the richest or poorest family but they said they couldn't afford to get me a iphone 5. I did find some contracts for only £27/pm

Won't the 4s be going out of date soon? This sounds stupid but i don't really want to go to school with it because most of my friends have got 5's. They might think i'm poor or something.

Sorry if this sounded very snobby. I aren't ungrateful. I'm very lucky to receive a new phone!

Added (1). i don't just mean the 5 i mean the 5. 5c and 5s
