Unlock solution for ios 6.1.3?

Is the falwok sim 6.1.3 legit? Or is it fake? I need to unlock my iphone 4s verizon on ios 6.1.3

Added (1). I currently was using gpp sim (gevey) on 6.1 and it updated to ios 6.1.3 and it never gave me a warning
and it will work on tmobile

Its fake. An unlocked verizoniphone is useless, can only be used on verizon or pageplus
