DC300 yeah, I replaced one screen myself, not that it was that hard, but for the little I saved, no thanks.
I had a new Nokia phone and just had to open it up to see the battery. I tried to pry the case open and cracked the glass. Two days old. I found a you tube video on how to fix it and got one off of ebay for $12 bucks and changed it. I found two cracked phones on ebay dirt cheap and bought those for my wife and a spare. I had a Motorla phone with a "non-replaceable" battery that was tanking and I found a video and battery on ebay. A bit more involved than the digitizer but doable. I ended up changing phones.
