Just upgraded my iPad and all went well. But strangely my iPhone 3GS did start the download on its own... Not a big deal as I was going to do it, but I still wonder.
I have to say that I picked up my iPhone a bit earlier and saw that the battery was at 6%. Odd since it was fully charged this morning. But I received a calendar invitation during the day and it looks like the iPhone got in a frenzy loop until I acknowledged the invitation. So I think that what drained the battery. But as I was trying to fix that issue, there was a notification that I clicked without looking at what it saying, thinking it was telling me that the battery level was low... maybe it asked me if I wanted to upgrade to 5.0.1...
