Dan O & Suzanne, hold the cable in the socket and put a dab of hot glue on both sides, It's non-conductive and should hold...worked for me.
Good catch of the incomplete unlocking instructions. ;P
I used this guide, to replace the two 256mb ram cards with the max. two 1gb cards, because of the great photos...much better than a video. But if I didn't have to upgrade the memory, all I would've done is remove the airport antenna, the frame screws and the thermal sensor cable and lift the drive up enough to clear the battery. And I did replace the CR2032 battery while I was at it.
Thanks Walter, good job!
