This is only the alpha version of this app, but it is the most wanted and requested application for the iphone. http://www.monsterandfriends.com/
have released the alpha much to my delight, it called Drunknbass and for now i would suggest registering with the site so you can be notified of the full release and alos get the link to download the app. for now you have to manually install it, so that means either using WinSCP or iBrickr.
With iBrickr, navigate to your Applications folder and create a folder called Drunknbass.app and upload all the files in the that folder on your iphone that are in the Drunknbass.app from the zip you download. You may have a problem with permissions, so you may need to install Terminal-vt100 or Finder and set permissions with that.
Using WinSCP and OpenSSH, it’s basicaly the same, navigate to the applications folder, and upload the entire Drunknbass.app to the applications folder and set full permissions (0755)
