What is the best theme using Winterboard for the iPhone 4/4s? GlasKlart HD in my opinion is one of the nicest themes that can be installed on a jailbroken iPhone 4/4s. The purpose of this post is not to go into how to install this theme on iOS 5.0/5.0.1. This post has been created for the purpose of requesting icons that you are missing in order to complete your entire theme. For those of you who haven’t heard of this theme I suggest doing a google search to find out more information.
