You know, I actually did a search. iFail.
Cheers, Scutchio. Presume there are planty of online tutorials for doing it?
I did a search and couldn't find it, either. Had to manually find the f*cking thread.
Yeah there's plenty of tutorials if you're going to DIY. Basically, you get the tool kit with the screen you order (be it the cheap one, or a more expensive one - still cheaper than other options). You take the screen off and simply unclip all the little components, carefully. Then place the new screen along with the components back in place. I'd recommend going for the more expensive option of the two I listed, as it's a genuine part I believe, rather than a potentially poor screen of the cheaper version.
As said though, plenty of guides online, yes. I've had mine open about 12 times now for various things (external speaker replacement, camera not working, cracked screen).
You can actually get just a replacement screen for about £7, but it's a pain in the arse to put in, as you need to fuse the screen on and solder the components back in, whereas with a replacement screen assembly with components already installed, it's simply a case of unclipping and slotting in.
