For businesses with
fewer than 500 employees, 34% reported using iPhones
compared to 38% using RIM, indicating iPhone is making
inroads among business users [5]. Finally, it is important to
look at the market shares and intentions to switch for AT&T,
the wireless carrier that provides iPhone services in the US.
From July 2007 (the launch of iPhone) to December 2008,
AT&T’s market share increased from 28% to 31%, while
Verizon gained only 1% over the same time period [6-7].
