So I followed the new guides for virginizing/upgrading/preparing/unlocking an already unlocked iPhone and it all worked.

There are a few issues though. Internet browsing and email both work fine, but Apollo won't connect to either my AIM or MSN account, and the YouTube app can't connect. I entered the same APN as before, internet2.voicestream.com, also tried wap.voicestream.com but it still doesn't work. Any ideas or known issues here?

Also, Installer won't uninstall the old or install the new version of SummerBoard, it keeps saying "Error during uninstall script execution!" when I try to uninstall the old version, and "Firmware 1.1.1 is required for this version of SummerBoard!" Same error when trying to uninstall Taskbar Notifier. Is this a common issue?
