Might seem like a dumb question but the update to ICS still preserves all the icons and stuff on the home screens right??
I found that I had to delete some of my widgets and add them again. You might also have to download "Rescan SD Card!" to put your pictures back in your Gallery. I had to do this, I'm not too sure if you'll have to.
