You need two things. The patched Springboard binary so the phone will always show AT&T no matter what carrier you're with, and also Customize so you can change to AT&T logo to whatever you like. Do a search and both binaries (1.0.2 and 1.1.1) are available for download.
For youtube, you need the patched lockdownd and 3 preference files, also available for download from the downloads section.
