So I restored my phone and upgraded to 1.1.3 with the hope that the upcoming SDK will bring many of those back in the fold. However, before I restored, I had already performed several minor hacks that seem to have been retained in the aftermath of the 1.1.3 update.
Specifically, this hidden preferences hack still allows me to touch the battery icon in the top right corner and the numeric battery level is displayed in place of the icon. Also, the custom carrier name was not touched at all. I used this phone app to modify it.
