No doubt verizon sales gave apple a bump, but:
This morning, before the opening Bell, Verizon released first quarter earnings results, finally disclosing iPhone 4 activations -- 2.2 million since the device's February 11 launch. [...] During calendar Q1 2011, AT&T and Verizon activations -- 5.8 million -- accounted for 37 percent of the 18.647 million iPhones sold by Apple, that's up from 30 percent a year earlier.
So verizon activations accounted for 2.2M out of 18.6M iphone activations or ~12%. You'd need to dilute that more for ipads and ipods, presumably leaving you with less than 10% of the sales volume. Impressive, but not nearly enough to explain a 50% jump.

iCrack doesn't have the same feel as Crackberry though...
