Following this guide, while trying to "flip up the white plastic tab", it broke (it is the BLACK one that should be flipped) and now I have a 600 EUR paperweight.
On my 3G, there is both a white & black plastic tab; it is the BLACK one that needs to be flipped up 90 degrees...
Normally iFixIt is awesome with the details, but this oversight left me sad, annoyed, and without an iPhone :( :( :(
Quote from M R:
That's not right, just put my iPhone in parts and on the 3G it's definitly a white plastic which should be flipped!!
Guide worked like a charm!
Thx for this guys!
Perhaps I wasn't clear; some have white and some have black; consider yourself one of the lucky ones! This oversight can be costly otherwise.
