At the time of the Verizon iPhone launch just over a month ago, we pointed to a live tracker set up by mobile ad firm Chitika measuring the balance of AT&T and Verizon devices registering on its network. At the time, just one day after the device launched to the general public, the Verizon iPhone accounted for 3% of the U.S. iPhone base as measured over a rolling 24-hour window.
Chitika has continued to monitor the iPhone balance in the U.S., and today reported that the Verizon iPhone now accounts for 12.7%, or over 1/8th of the U.S. iPhone base, although the Verizon iPhone’s share has since sunk to 11.9% due to measurement fluctuations over time.
Apple has of course been expanding its partnership with Verizon in recent months, beginning with packages including the original iPad and a MiFi hotspot device before moving on to the iPhone 4 last month. And just last Friday, Apple debuted the second-generation iPad, which comes in a series of models directly compatible with Verizon’s network.
