ceSnipURL is a free utility to convert long URLs into short URLs, which comes in handy for sites like Twitter and Facebook where you have a very limited number of characters to update your status. It automatically uses URLs from the clipboard and once converted, puts them back on the clipboard so you can paste them into your app.
I know a lot of Twitter clients for the Windows Mobile already do this, but some of us prefer to use SMS and PIE for our twitter needs, so this allows us a quick way to shorten URLs before posting. I cannot tell from the site if this works on Standard or not. The screenshot is of a Pro (touch-screen) device. If anyone with a Standard device tries this, let us know how it works.
