From what I have seen (on the nokia tutorial/instructional video) taking the
7650 requires a specialist "cradle" to drop the phone into and slide the
back off....

Try googling along the lines of "nokia 7650 disassembly video"
You may find the same video...

You can do it with two small/medium screwdrivers aswell. carefully slip them
down the sides of the 7650 ( where the silver front meets the rear brown)
until the sides starts to bow out slighty, carefully with one hand on one
part and the other hand on the other part of the phone
wiggle and twist the phone housing's whilst pulling the two halves apart. do
this slowly and carefully because if to pull them too quickly you may risk
ripping the ribbon cable that connects to too parts together..
when I can't find my 7650 tool ( cheap u shaped piece of plastic) I have
used this method many a time when changing or cleaning screen with no
problems, Just take your time  :)

???  What link?

There are instructions on the UselessInfo site in my sig, but it's not the
easiest of phones to dismantle.
