I'm guessing that Sprint's number of iPhones sold, if they mirror VZ's trend, will be about 1.2 million.
However, Sprint had a lower percentage decline thant Verizon from 4Q 2011 to 1Q 2012... so it may be that while the overall iPhone sales are declining because people are anticipating a new iPhone, more people who are buying new are going one to Sprint... So we may see Sprint's sales numbers of the iPhone kill VZ and ATT in terms of showing a relative marketshare increase.
