Got an iPhone 4 on AT&T (USA), currently on iOS 4.1. To update to 5.0.1 JB, can I just update to 5.0.1 via iTunes, then follow the iClarified guide (http://iclarified.com/entry/index.php?enid=19014)? There's nothing special I need to do during the update from 4.1 (JB) to 5.0.1 (non JB)? I don't need to preserve my baseband, since I'm not unlocked. Thanks!
