Muller spots the culprit in the margin drop. He notes that this is money set aside and may have been in anticipation of returns of the iPhone 4 due to antennagate. Note how in 3Q cost of claims was 155 and accruals were 157, about a 1:1 ratio whereas in 4Q costs were 286 and accruals were 457 about 1:1.6.

It’s possible that if the costs this quarter do not materialize then we could see a margin upside surprise.
