When I was in Canada, I dropped my iPhone 3GS in a water drain, and it essentially got drenched. After submerging it in rice for seven hours and letting it sit for three weeks, it works absolutely fine - albeit one small problem. The backlight is completely non-functional. It won't react to anything at all, I've restored, everything. Now, all that's left is asking you guys for help. HELP! How can I get my backlight to work again? Is it fixable?
