Practical scenario:

So on Sunday I dropped my iPhone 3G in the toilet.

I grabbed it out, lovingly towel dried it, sat it in rice, hairdryered it then put it in a vaccum desiccator for 12 hours!

Today I turned it on for the first time at IT WORKS! It still has all my data, surfs the net and can make phonecalls but…

The screen looks grey. I can still see all the icons (in colour) but everything looks grey. On closer examination it seems like there are loads on tiny white horizontal lines on the scree.

Has anyone else had this happen to them? Is this fixable with a new screen?

Any advice would be greatly appreciated.
