Bad logic board on 4S

[jerryjohn]

I finally got my upgrade to a 4S in July of this year,
unfortunately I took it in swimming which wasn't good.
It is diagnosed with a bad logic board. My question is...
Can the logic board be replaced? If so, how expensive is
the replacement?

Honestly... a replacement logic board is going to run you at least $200+. And that's most likely for El Cheapo knocko-offs.
