So I just rooted my DX today and I don't know what to do with it. I rooted after official 2.2 was released so can anyone help me out?
Then why did you root it?
J/K, first thing I'd do is to make some Backups. Titanium Backup for your apps and data, and then install Kousch's Bootstrapper and Clockwork Mod Recovery from Rom Manager to make some total backups of your device.
a little obsessive...
