This is an excellent thread and please leave it open. I have replaced screen on i9000 before in the same way.....i did crunch a screen on the first one i tried ( didn't realise they were stuck together)
don't see the harm in having a go....as you have to pay the full price for a new digitizer+ screen anyway....so if it breaks foook it!! if not , you are sorted.
people who don't want to help or cant provide anything usefull should not post. That way the thread will stay clean.
I will be attempting to replace the casing on an s2.....hopefully it will go ok.
