I did the 3.0.1 software update last night and at first it didn't work. Unknown error. Put my iPhone into DFU mode and did a restore, did a recovery from a back-up I made a few minutes earlier and did the update. I left the room, only to find a broken iPhone screen when I came back !!! The top 25% actually shows anything, the rest of the screen is just white. I left the iPhone off for a few hours when I was asleep, hoping that would fix it, but it didn't. I'll post some pictures when I get back from work and when I cool down.
