Flickup is an application for uploading photos to Flickr directly from iPhone using the same interfaces as the built-in camera and photo albums applications.

With Flickup, you can geotag photos with one touch and set defaults for even quicker uploads. You can also send links to your images directly to Twitterrific.

Note: Photos taken with Flickup are uploaded at full size. Photos from the photo albums are uploaded at 640x480 because of a limitation in Apple's API. EXIF data is stripped from all photos because of a limitation in Apple's API.
