Hi, I don't reallt have answer to your question, only to the second one. Can you replace digitizer without removing the lcd? The answer is yes and no. Not really, but you can only remove the lcd itself, not the metal plate holder thingie it sits in. The lcd itself has virtually no glue on it, whereas the plate is seated with a massive amount. Obviosly the problem is that while trying to open it, you will break the lcd. So only take out the lcd (the plastic part) and the metal stays. Then you can play with the metal when there is nothing you can possibly break. Hope it helps
