What is this?
The Kpw2 does not (yet) have an end-user Jailbreak procedure.
These items are listed as "Release Candidates" for that reason, they may have to be changed once an end-user Jailbreak is found.
To install these packages on a Kpw2 requires that the Mobile Read developer's certificate (A.K.A: device jailbreak) must be installed on the Kpw2.
Currently, the only way to do that is by using the serial port.
Using the serial port requires disassembly of the Kpw2 and a fair bit of technical knowledge.
Not for the faint of heart or in-experienced user.
Candidates have been tested on at least one Kpw2 but are not intended for general use (yet).
