For current users of Tumblr, you're probably familiar with the third party native client Trapeez by Kisai Labs. This application allows users to view their feed, reblog, like posts, search tags, post photos & text, and much more right from their BlackBerry. It also features the ability to choose which blog to post to, modify publish options (Publish Now, Add to Queue, Save as Draft, or Private), and choose a format (HTML, Plain Text, or Markdown).
Once you've installed the beta, you'll find that this version comes with the following updates and fixes.
Fixes in this release
If you haven't tried Trapeez yet, this is certainly the time to do so. I've been using the beta version and performance wise it has been running smooth. You can go ahead and grab it directly from the BlackBerry Beta Zone app. More importantly, don't forget to submit your feedback, including bug reports and feature requests, from there as well.
You can sign up for a BlackBerry Beta Zone account for free. Please note, that Beta Zone is not available in all regions.
