I have a 4th gen iPod touch that recently managed to escape my hand and embrace the floor. While the situation was rather comical, now the glass screen is broken. Everything else works fine, including the touchscreen, but it has the so-called "Spiderman" cracks all over half the screen.
I've called Apple to see if they'll fix it, but it's too expensive, so I'm not going to do it. I also don't think I'd trust myself or an unofficial repair shop to do it. So my question is, what can I do to prevent further cracking? There are some places where it looks like pieces of glass could fall off easily. Is there any way to protect what's left of it while making sure the touch sensitivity still works on the whole screen?
