6230 - save internal memory?

My phone has died. It refuses to turn itself on. I've already harrassed Google into giving me sites that could be of some assistance, but to no avail. I can only agree to it being water damage (coz I have taken my phone into the bathroom while I showered a few times, and it was kinda... raining 10mins before I realised my phone was dead).

I have attempted to clean the PCB using Chunkhead's Guide To Water Damage (though I didn't soak it, I just squirted). Funnily enough, I hadn't noticed any signs of corrosion, but I wouldn't know if all [supposedly] water-damaged phones show these. I haven't given up hope, but I do have an inquiry:

Is there any way for me to retrieve the data saved on the internal memory?

I would go so far as to solder the chip onto another phone (the one time I deny my phone backup, I manage to kill it, so yes, I'm somewhat desperate). I doubt my memory has been damaged, I just think it's a power problem (my battery works fine in other phones, another battery doesn't work in mine).

Appreciated :-D
