Analysts usually take Apple’s quarterly guidance with a grain of salt, given that the company tends to lowball its estimates.

UBS analyst Maynard Um expects iPhone unit sales to jump this quarter if Apple’s international phone carriers plan comes out without a hitch, reports Tiernan Ray for Barron’s. Um holds a Buy rating and a $510 price target.

Jefferey Fidacaro with Susquehanna Investment Group holds a positive rating and a $535 price target. Fidacara attributes the lower Q3 iPhone numbers to the “push-out of a refresh past the typical June time frame [for iPhone introductions.]”
