Extended the iPad life and taught my son a couple of things
Broken screen on the iPad2, it's my wife's artist studio machine and it took a tumble while she was moving around canvases. It had an interesting straight line crack from side-to-side which in turn contained the crazing to 25% of the glass.
Repair guide was helpful and accurate. The plastic pry tool left a bit to be desired as it deformed and got boogered pretty quickly. Found an exacto blade to be helpful but requires a deft hand.
I'm not sure that it's possible to remove the glass without killing the wifi antenna. I suppose it's possible with practice but I'm glad I followed the advice to purchase this together with the front panel kit. Not sure why adhesive is needed on frame and glass sides of the antenna but what do I know?
I inadvertently failed to tighten the logic board screws which leads to an unexpected result of the iPad rebooting whenever you tilt the device. Luckily the front panel came off easily and the screw tightening fixed the issue.
1)Heat gun is a very useful additional tool.
2)Duct tape had enough adhesion to be useful in removing crazed glass slivers in intact chunks (I read a number of reports that packing tape didn't help).
3)Eye glass cleaning micro-cloth is a great way to clean LCD and both sides of glass
4)Shared the experience with my 11 year old son. He's a good extra set of hands and expert micro-screw turner/organizer. Micro-screw tightener was my job (which I failed as per above.)
