it's not the nicest job someone could do - i didn't like it
had to do it last weekend and it was horrible.
all that sticky crap - you have to use a hair dryer to get the pieces apart (everything seems to be extremely fragile) - most of the time the lcd will break if you try to remove the digitizer, they are "glued" together - thats why i recommend the complete lcd/digitizer unit.
since you have to disassemble it anyway - remove the digitizer from "your" phone and you will see if it's connected or soldered to the mainboard ;-)
but be careful - i've seen many ebay offers with the wrong part/description!!
