I think Facebook have been very sneaky with the latest 1.6 release of their Android application.
I noticed that upon first launching the application, the wall post section looked the same as previous versions but upon going back into the application, the layout of the wall posts were very different.
For example, friend avatars were smaller, picture thumb nails for content being posted was much larger, the comment/like information was on a baby clue backfround and there's also a blue + button which loads a hovering menu to add a comment or like a post when you click on it.
I also noticed when clicking on news feed, another window will launch extremely quickly and come into focus and recently, the wall post section of the application appears to get stuck in a refresh loop. This is confirmed by other comments on the App Market.
I decided to try the touch.facebook.com website, the same refresh bug exists and the layout is exactly as described above. So the 1.6 Facebook application appears to be just a wrapper for touch.facebook.com, at least for the news feed section.... pretty poor, I always remember the iOS Facebook application being very reliable and stable and we're talking 18+ months ago.
