like the boss said, if your phone ever gets wet, taking the battery out immediately is the best approach. ebay has the 5200 for $60-90 used if you look around. "service required" is bad to see on a phone....usually means its fried for good. Sometimes phones will come out of carkit mode but its usually within 3-4 days....if its been longer i doubt theres any hope...

There really is nothing that can be done for a water damaged phone.

I know this isn't going to help now, but you should not have done anything to the phone except took the battery out and dried it off...then let it sit someplace for like three days before attempting to put the battery back in and trying it out.

The best thing is to just tell your mom and get it over with.

You can try and check places like our For Sale/Trade forum to see if somebody is selling a 5200 for cheap, or even Ebay.
