I maybe isolated iwth this problem but I thought I'd check anyway.

I have jailbroken 3.0 with redsnow which installed ICY and Cydia.

Firstly Cydia wouldn't work as the updates it required won't install, it keeps bringing up this error.

So no problem I just used ICY and got Installo*us on.

Now I have noticed that a few of the icons on the springbord appear scrambled, most often it is the Maps icon. After selecting a new theme in winterboard it restores however after a while the image scrambles again.

I have a few more gripes about this 3.0 being jailbroken but I am sure the devteam will iron these out soon.
