Getting an iphone 5 unlocked? Yes or no?

I just received an iphone 5 locked to rogers, i was thinking of selling it and buying a new unlocked one. However now i'm thinking of just getting the phone unlocked
there's someone who told me he will factory unlock it for me for 130$, so my question is does factory unlocking it by a guy going to harm a brand new phone that is unused? So should i do it or not?

You might be able to do so on line for way less. I got a phone unlocked for under $20.00. Once unlocked you can use any service out there.
