If that's been done already, use a mini-USB cable and see if your PC will still recognize the phone as a storage device. If the phone boots but merely doesn't display the internals may still be accessible via your PC, etc. I can do this w/ my older HTC models. Drag and drop files as you need to. Using google you can find other instances of how folks have done this. Also ask at howardforums.com for more details on recovery services if you get to that point ($$).
SMS will likely be a bit trickier. You may have to have a rooted device in order to be able to access the part of the file structure where they are stored. Sites like XDA developers forum can assist you in doing this. But there are also programs such as SMS backup & restore that you might also try. Look in the Android forum for info on this one.
I have an HTC inspire that got wet. It will power up and go to the home screen, but will not let me go past that screen. I am not sure if the screen isn't responding or if something inside is fried. What I am wanting to do is send my phone to someone who can pull the data off of the phone's internal memory. I believe my SMS messages are all stored on the internal memory. Any other info that could be pulled off would be good as well. I am having a difficult time finding the right people to send it to. Most are telling me between $250 to $1700 dollars. The information isn't worht that much to me and was wondering if anybody knows who could help.
