Should I Update Carrier Settings in iTunes?

[minichrispy]

I currently have a CDMA iPhone unlocked on MetroPCS with talk/text/messaging/data/mms all working (I used iPhoneCDMATool). Ever since I unlocked it, I've been getting this message in iTunes and just wanted to be sure about whether or not I should install it. Will updating the carrier settings re-install the Verizon settings, or is it an actual update for the MetroPCS settings? Thanks in advance for the help.
