Cracked display again & home button working intermittantly
Great, until I found the home button logic board connector not connected to the logic board. Had to order the dock connector sub assembly.
This was replacement screen #2. I've got the process down to about 1/2 hour.
Inadvisable to do in the presence of 2 1/2 year olds!
Make sure all sub assembly parts are not effected by drops (shock stress)
