How to Factory unlock iphone4 16Gb at&t?

My cousin gave me his iphone4 which is locked to at&t USA. I know redsn0w use however with this iphone 7.0.4 iOS - it is returning me an error "Blobs are corrupted". With no help on it, I decided to see options for factory unlock however the price are real high. I heard people getting free factory unlock code, where I can find these, if any exists? I also downloaded a software iPhone 4 unlocker v1.0 however to get serial key for this, I have to complete a survey [which I'm doing but still not getting serial key file from FileIce website]

Any help, especially when I would not have to spend anything?

Nervous, Paranoid, Possible Cheating?

I've been dating my boyfriend for almost 3 years now, and juts recently, we have both started back to college, have full time jobs, and don't see each other as often as i'd like. I'm not usually this paranoid, but i've been getting the idea that he may be cheating on me, or talking to someone without me knowing.

He has never cheated on anyone before, and he has been honest with me for the past 3 years. Although, he got a new Iphone this past year and has had it for quite a few months. I have never been on the phone and don't know his password. Also, he recently changed his Facebook password without letting me know (Yes I was trying to snoop, I know how bad that looks…) and I can't figure out why.

I want to confront him about it without seeming crazy. What should I do? What should I ask him? We've never had problems like this before and I really don't know if i'm right, or just a bad feeling… Please help.
