Upgraded WordPress / WordPress iPhone app

I upgraded WordPress today to version 2.6 which I had been putting off for some time.  The upgrade was surprisingly easy, but there are a few things that aren't working after the upgrade.  My Flickr photo plugin appears to be activated, but doesn't seem to be serving images, or causes the browser not to load anything except the header.
I'm still trying to figure out that piece, but everything else seems to be working correctly.  The upgrade wasn't supposed to provide a huge amount of new features, but there are a few nice things such as the word count, Google Gears compatibility to make things a little faster/smoother, and a few other things.
I also started using the WordPress app for the iPhone and have posted a few times with it, even with pictures.  I started using it with my first gen iPhone and it seemed to work just fine for standard posts, although it was a bit slow.  Uploading pictures is not tenable with the first gen iPhone – it takes too long over the EDGE network.  Wireless of course works fine.
Overall, I love WordPress and have had no problems with the core software.
