I'm probably in the minority in not using springtomize or tweaks to get rid of icon labels, or changing or removing my "slide to" text. I just prefer to add source to my .plist or bundles to remove icon labels, or edit/remove "slide to" text.
As for editing or removing the "slide to" text... you can try the following...
example:
/var/stash/themexxx/base.theme or LS.theme/Bundles/com.apple.springboard
Within the the "com.apple.springboard" create a folder named "en.lproj". Next, create a file named "SpringBoard.strings", and copy/paste the following source in it:
PHP:
"AWAY_LOCK_LABEL" = "slide to unlock";
"POWER_DOWN_LOCK_LABEL" = "slide to shut down";
"SLIDE_TO_ANSWER" = "slide to answer";
You can change the text above to your preferences.
If you want to take out the "slide to unlock" and "slide to answer" text, just make the following edits in the "SpringBoard.strings" file:
PHP:
"AWAY_LOCK_LABEL" = "";
"POWER_DOWN_LOCK_LABEL" = "slide to shut down";
"SLIDE_TO_ANSWER" = "";
I just
remove the slide to unlock text on my lock screen... and the example above is they way I do it.
Anyhow... hope this helps...
