I've been using the iPhone app to create blogs. I've just upgraded my phone to 4S and iOS 5. When I launched the app I was asked to re-enter my password. I did, and signed on successfully. Then I made a new entry, went to upload a picture to the entry. It uploaded (showed upload 100%), but then gave me an alert "Sorry upload failed, bad login/pass combination". I couldn't find any settings to refresh this, but the fact that I was accesing my blogs seems to indicate that you have a bug in the process. I guess I'll delete the app and download a fresh copy... to see if that fixes the problem.
The blog I need help with is amatteroflight.wordpress.com.
