Hey, I just got my second hand Kindle 3 Keyboard with 3g, It has 3.3 fw usa, I'd like to use JB, LP, keyboard hack, custom screensaver, PDF reader (based on muPDF, GPLv3), CoolReader 3. Is this mods and hacks worsk with 3.4? So am I just apply 3.4 than the mods or add the mods and apply the update?
