I'm extremely excited to announce that the latest version of MobileNotifier - a new release of beta2 "Bountiful Bran Flakes" - supports push notifications entirely now. Read the full text of notifications, along with their sending app.

I also have a repository - add phajas.xen.prgmr.com/repo to Cydia, and you can install the latest version of MobileNotifier without compiling anything.
