Iphone 4s upgrade and jailbreak?

My iphone 4s is network locked to Globe. And i had it unlocked so i can use other networks. I was wondering if i would upgrade my ios to the newer one or if i would jailbreak it, would it affect the network locked etc of the phone? Will it go back on being locked?

May be it effects.gave your phone to professionals.

No, it will still remain unlock. If it has been factory unlock, then you won't lose the unlock even if you reset, restore, jailbreak and update its ios. So no need to worry about it.
