No, if your device is officially unlocked (Maxis/Celcom/Digi or whatever factory unlocked location), then as long as there is an application that can jailbreak the current firmware, you're good to go.
So if you're on a factory unlocked device, you can use redsn0w, sn0wbreeze, pwnagetool ... whatever you like.
For those with LOCKED set (like AT&T set from the US, Japanese iPhone set, UK set), then you have to be extra careful with which JB program you want to use. NEVER use redsn0w if you have a locked set. It will always be either sn0wbreeze (for windows) or pwnagetool (for Mac)
i second this. been playing with a set from Japan since yesterday. only now just now get to jb + unlock . quite hard
