I repeat, "The only current jailbreak for the PW3 (or the Voyage, or the
KT2) is the serial jailbreak described in the relevant sticky thread here."
The current $49 "Basic" Kindle is what we call the KT2 (Kindle Touch 2) on account of Amazon calls about half their Kindles the "All-New Basic Kindle".
You will need the Kindle Touch (first ever Kindle to have a touch screen) or earlier in order to use the easy drag-and-drop jailbreak, You can probably buy it used.
Or, @madagascaradam reported that the
PW1 only can still be downgraded via the forced-reboot trick:
