...to Cydia. Then do a search for Push Doctor to locate the package, install, and confirm. From weblog Addictive Tips:
Once the package is installed, you're done. It won't show up as any app on your springboard or under the Settings app. What this package does is simply adding the valid, unique certificates for your hacktivated iPhone. Try any application with push notification support to ensure working of the package.
You can use Push Doctor on any unlocked iPhone running firmware 3.1.3 or 3.1.2.
