Changing UI Element Of iPhone

Most of you know that i pretty much don’t like iPhone themes, and that is because
1. Most of them are butt-ugly.
2. The ones i like, takes too much RAM and I prefer having my iPhone theme free. I got to admit though, that lately I’m flirting with a slightly modified version of GT theme found in Cydia store.

Well it seems I’m not the only “theme hater” out there, but sometimes there is the desire to customize the look and feel of your iPhone. That’s one of the benefits that comes once you jailbreak your iDevice , right? You still can customize every single UI element of your iDevice, without having to install any theme. If you have some badass graphics , all you need to do is to SSH into your iDevice, and replace the original files.
NOTE: backup everything
NOTE: be aware that some graphics may not be changed back to the original state. If that is the case, your only option is to restore your iDevice..
