23-12-2009 You can get the theme from Cydia (search "Chromiphone" in Cydia) I added it a while ago to the ModMyI Repo and forgot to update it here that you can install it from Cydia
To install, copy the folder 'Chromiphone.theme' to /Library/Themes/ on the iPhone/iPod Touch. Then open Winterboard and select 'Chromiphone' ------
All icons are painstakingly created by me (well, almost all of them, some of the icons I found on the net), All of them are custom shapes that I will upload after I finish with this theme.
This theme derived from Google Chrome's design, clean and very good looking, hence the name "Chromiphone"
Drop the .theme folder into /Library/Themes/ and enable it in Winterboard.
I don't have an iphone to test it, but if I remember correctly it should work.
I'm just replacing the lock/unlock sounds with empty sound file...
I heard there's a Chrome theme for Safari called Chromafari.
