I don't think it cost him anything. From where I was sitting, it just looked like the lollipop man saw Kimi coming, and got a bit ahead of the refueller in lifting the lollipop. Once he realised the pit stop wasn't complete he dropped the lollipop again, and then released Webber once it was done. I don't think it was an un-safe release, but it was very close, obviously because the lollipop man wasn't keen to let Kimi through un-contested..
Pretty sure the 'incident' they were investigating was on the straight, before the turn, where Kimi moved right. I don't think you can penalise him for that considering the fact that if he didn't move right, he would've rear ended Webber as he was gaining on him pretty quickly at that stage (KERS).
As for what happened on the exit of turn 1, as far as I'm concerned, 3 cars were racing, Kimi either copped a knock from the 3rd driver on the outside of the turn (Webber maybe?) or just got on the gas too hard and stepped it out which steered him into Vettel.
