Several analysts have expressed conflicting views on AT&T's iPhone exclusivity, and whether or not it will end in 2010 or be extended another year. Craig Moffett of Bernstein Research has raised his Verizon rating from Underperform to Neutral, in part because there may be little future for AT&T even if Verizon does not get the US iPhone. AT&T's growth will "sputter" without the iPhone as a guaranteed draw, says Moffett.
