Any thoughts?

May want to open it back up and make sure that that the cable from the antenna is connected to the logic circuit board.

It sounds more like the SIM card reader got damaged by being wet. Considering the cost of the phone versus the cost of replacing everything that's going to keep going bad after you replace the motherboard, I'd say the phone isn't worth repairing. A repair of everything will cost more than a new phone.
