Hi all
My Kindle PW2 came with FW 5.4.2.1

I have installed the following in the order
Jailbreak (and something which is supposed to help Jailbreak survive an update)
MKK
KUAL
KO-Reader

I have the option to update to FW 5.4.5.1
I'm just worried that one of these won't be supported.

Someone please tell if I should go ahead and update or not.

EDIT: Well, Kindle went ahead and updated itself
The Jailbreak survived and I just had to install MKK again. KUAL and KO-Reader then became functional as they were before.
