Cleaning inside of the screen?
I recently purchased the iPhone 5 and will be looking to sell my iPhone 4. Before I do so I need to clean the inside of the screen as sweat has gotten under it and seems to have crystallized. My questions are now, (1) is it worth it to do, (2) is it very difficult? From looking at this site, it seems that I will need to remove nearly all of the components to get to the underside of the screen and if that's the case, it may not be worth the time.
Is this a good question?
