I have a question, is it possible to take away the time and date Without installing tweaks from cydia, and Without replacing files in the iphone folders like /System/Library/Fonts/Caches/ then remove the LockClock.ttf file and change it to yours.

And Custom Keyboard, how to change the colour of the keyboard Without installing tweaks(eg. Color Keyboard) from cydia too.

I would like to use the normal way like "Themes/MyThemes/'..........' "

'.........' = where I should put the file for removing time and date on lockscreen, and the theme for keyboard
