A few days ago I update a few apps, as I recall they were: MyWi, Activator, and Circuitous. Afterwards the display of icons on my screen was reset with smaller icons with more space between. Also the wallpaper is missing and in certain apps there seems to be a new theme in the menubar. Also the resolution of certain app screens seems to be altered with certain buttons not working unless I rotate to landscape mode. I reset Activator to default settings thinking that since that was one of the apps I updated maybe that was it and it fixes the problem until I restart and then it is back to the strangeness.
Also, in looking around the Cydia app manager for the first time in awhile I'm seeing all sorts of stuff listed there that I did not install?! Were these things installed as a part of the apps I did install?
