how to delete heroku deployment

i had deployed an app to heroku, called falling-sky-4350.
i deleted the app from heroku.com, then created a new app clientside

heroku create
Creating sharp-window-8814... done, stack is bamboo-mri-1.9.2
http://sharp-window-8814.heroku.com/ |
git@heroku.com:sharp-window-8814.git

when trying to push it again, it seems to be looking for the old app

git push heroku master

! No such app as falling-sky-4350

fatal: The remote end hung up unexpectedly

how can i resolve this?

Go into your git config for the project and edit the remote for heroku..
that should do it.
