If you share a lot of links from your Android phone (or would share more if it was easier) D Bitly is an unofficial Bitly client that makes short work of URL shrinking.
Not only can you shorten URLs with D Bitly but you can also access your URL shortening history at Bit.ly. Shared a link via IM or email earlier in the day and want to share it right now from your Android device? You can pull it up and one-click share it from D Bitly. Want to shorten a new URL? You can shorten it, share it, and add it to your shortened URL history.
