Edited to add: it's a 16GB phone with 3.91GB free
My 3g update was agonizingly long. I think something went wrong at some point and it went into a full restore cycle which seemed to take forever. I finally gave up watching the update and went to do something else. About an hour later it was almost finished. Total time probably around 1:45 - 2 hours. I'm getting an iPhone 4 today so I really didn't need to do the update; I was just curious to see a few of the changes.
