Try a reset (pull the battery) also double check your themes. One thing that I do IF things go weird is to set the theme to another theme and than change it back. This usually fixes many of the simple odd icon things that I see.

One other thing that I saw was I was able to get an 8100 theme to work on my phone…but it ended up crashing it…lesson learned: we have to wait until there are some custom themes for the 8800.
