Calendar Q2 iPhone (AAPL +0.6%) sales are trending towards ~30M (above a ~27M consensus), says Jefferies' Peter Misek in an info-packed note. Misek also: 1) Believes Apple has set aggressive Q3 and Q4 iPhone build plans, with nearly half the Q4 builds involving a cheaper iPhone. 2) States the iPad Mini is "cannibalizing more than expected," and expects the current model to be kept and discounted after a retina model launches. 3) Expects the 5th-gen iPad to be ~50% lighter and 30%-40% thinner. 4) Thinks AT&T (T) and Verizon (VZ) are talking with Chinese white-box OEMs about selling carrier-branded phones, in an effort to cut subsidy costs. 5) Believes consumer BlackBerry Z10 (BBRY +0.5%) sales have slowed, but that Q10 sales are better than expected.
