Well, the 2.7 Beta of WordPress for iOS fixes a major problem I had with v2.6.6. How? Before, the app kept giving me grief over my self-signed SSL certificate. Today, I decided to install the beta by checking out the SVN trunk and compiling the app for my iPhone (and then self-signing that and installing it on my jailbroken device). FYI, this post was written in the now-usable WordPress for iOS app on my iPhone 4.
Expect the number of posts (and the number of posts with pictures) to increase dramatically. Hey, maybe I'll be able to surpass the number of posts MakerBlock averages monthly (if I ever upgrade my server)!
