And then...

staff:

Inspired by Wordpress’ seriously clever use of Loren Brichter’s new Tweetie options, we’re launching our own Tweetie and Twitterrific compatible API. This Twitter-like API should make it easy for a lot of existing Twitter clients to start supporting Tumblr.

The really cool thing - because our following models follow a lot of the same principles, we’ve been able to take advantage of a ton of native features:

• Retweeting = Reblogging
• Replying = Reblogging w/ commentary
• Favoriting = Liking
• “@david” = ”http://david.tumblr.com/”
• Conversations = Reblogs

To try out Tumblr in Tweetie 2, tap “Accounts” → “+” → enter your username and password → tap the gear icon → enter “http://tumblr.com/” in both fields.

For Twitterrific, tap ”Sources” → “Edit” → “Add a New Account” → enter your username and password → tap ”Advanced” → set “Base URL” to “http://tumblr.com/” and disable “SSL”.

Trying out Tumblr with Tweetie 2. With Tumblr-Twitter having same username but different passwords my Twitter account got Locked.

Update: I deleted all accounts in Tweetie, waited 60 minutes, set them up again and this time they all appear to have worked with no lock-out when trying to use Twitter.
