iPod touch Can you replace the Digitizer only on a 4G?

[Tazadoobii]

I've acquired an iPod Touch 4G for £20 (get in!). Only problem is, the digitizer is cracked. I've looked on eBay for replacements and it looks like buying the LCD & Digi together is the best option? If this is the case, why is this?

I'd rather just pay for a new Digitizer, assuming the hassle isn't much worse than putting both LCD and Digi together in one package?

Thanks guys

One piece

They are one bonded piece and cheap.

What in the world is a "digitizer"?

That refers to analog-to-digital conversion. Any ADC is done in iTunes. The iPod is strictly a digital device with the content in the digital domain already, although it does have a DAC for analog audio playback into the earbuds.

"Digitizer" sounds like a misnomer; nothing is ever "digitized" inside an iPod.
