So... I've recently jailbroken my KT3 with the WatchThis Software Jailbreak method, setting my device in English/UK English (something that I usually do anyways). And it worked just fine. Then I installed KUAL, KOreader and the screensavers hack.
The last one was working perfectly until I decided to chance the time of my device to match my time zone. Is there a way to make it work again? I would prefer to keep it in English, just changing the time zone
