IHS iSuppli claims Apple sold more smartphones than Samsung. Strategy Analytics claims the reverse (this is the one most news outlets are reporting, no surprise there). So which is it and why are the estimates so wildly off? I can only imagine what the 'analysts' and tech writers would say if Apple ever stopped publishing sales figures. Yet none of them seem to care that Samsung, HTC, Amazon etc. refuse to disclose sales. They just lap up any report that comes out, eve ones that compare estimated shipments to actual sales.
