I got a little bored tonight, so I added in support on Snipit.me for Tweetie 2.x on the iPhone (for URL shortening, haven’t done images yet).  I’m pretty much the main user of the service (a few friends use it as well just because they trust me to keep it running for the forseeable future).  Anyhow, if you’d like to set this up, inside of Tweetie on your iPhone:

1. Go to Accounts view
2. Settings in the lower left
3. Services
4. URL Shortening
5. Custom
6. http://snipit.me/?url=%@
7. Save in the upper right

That should do it.  Enjoy :)
