I am not sure how is this related to the delayed shipments of some N900 orders (amazon etc.) but Nokia has had some problems with getting enough components.

Seems like many people are waiting for a long time also for their iphone 3gs to arrive, at least here in Finland. For example buddy of mine has waited 3 months for his 3GS.

Can it be related to the shortage of Cortex-A8? Who knows.
