I buy a Paperwhite with 5.3.1, jailbreak, JBPatch (Enhance Dictionary, Modify Reader fonts, Fix layout, Modify margins),KUAL, ALT_Fonts and Collections Manager and I am happy because I never turn on WIFI
I want to ask all the people that complain about hack's problems with update:
What the update give you better than the hacks I mentioned?
Ixtab make a fabulous work that make a Kindle a much better machine and we have to be very thankful with him.
It is a pitty that this great Forum only talk about complains.
Amazon will continue to update until nothing of the hacks function.
Please, install 5.3.1 firmware (or whatever you like) and don't complain any more!!
Thank you Ixtab again.
