This screen is fantastic value, and in general it works, which is great! There are just two issues with it:
1. It doesn't come with the tiny metal gauze stuck on where the ear-mic is. I didn't realise this until after fitting. Anyone whose fitted one will realise what a pain that is!
2. My screen now has a thin white line down the left hand side where it looks like one pixel-worth is dead the whole way down. Again, if anyone thinks I'm taking the whole thing apart again to return it they're kidding themselves.
All in all, for 22 quid it's fine!
A little note to people replacing it: you may need to turn off and on 3G and iMessage after the replacement procedure as neither we're fully working on mine until I did so. Also, if you get it back together and the wifi is terrible check out the notes on step 5 of the ifixit tear down pages.
