As much as I'd like to share this with all of you nice people in this subreddit, it's not as easy as just unzipping, downloading to your theme, respringing, and seeing all your Settings icons magically change. Yes, SOME of it would be that simple but only about 40%. I only did icons for the App Store Apps I have and all of the other pictures in those bundle directories are from themes I have purchased so I'm not sure if I can actually "share" other people's work. I already got in trouble for that once here on this subreddit. Second, to do the Tweak Settings icons, it requires A LOT of searching for the right file (i used iFUNBOX to do this) and overwriting it with the correctly sized 58x58 pixel .png file which I also have for all of the Tweaks you see in the link photos. MOST of these can be found in your Library/PreferenceBundles dir. but not all of them. The search feature in ifunBox will be your best friend for those hard to find icons.
Unfortunately, it still requires a ton of work on your end. Work most people will not want to do or figure out how to do. It's time consuming, aggravating, but still really awesome when done BUT requires you to have some general knowledge of how to navigate through your phone's raw system files. There was lots of trial and error involved when I did it and it still requires me to go in and update each .png file whenever I update a tweak or install a new one. The hard part is now done though, so updating icons for a tweak or app here or there will be much easier now.
Also, this is for an iPhone 6 only which means I didn't resize or edit any .png files other than the [email protected] files (this pertains specifically to the Tweak Settings icons, but also some of the App Store Apps b/c I removed all of the [email protected] files).
If you know what you're doing and understand this is a custom job done by me, in my free time, for my phone and theme, and still want the files, shoot me a PM and I'll send them over. I don't want to be responsible for anyone messing their current theme up though but will do my best in telling you what goes where. Like I said, though, it still involves alot of work on your end to make it right and will probably include you making your own icons for your own apps I do not have.
Cheers and Happy Themeing!
