BB Pearl 8100 :: Retrieve Text Messages - Backlight Does Not Work?

I have an 8100 series T-Mobile Blackberry. It went swimming a couple of months ago, but after drying the phone out in a bag of rice for 2 days, it started working again. After that, I began having intermittent problems with the backlight...sometimes it would grow very dim to the point that it would be difficult to read the screen, other times it wouldn't work at all even though the phone was powered up. Eventually it stopped working completely and I got a new 8520 from T-Mobile which works great.However, I desperately need to retrieve some old text messages that are stored on the 8100. They are going to be used in a legal case (if I can get to them) and I need to get them quickly if possible. Is there a way to do this?
