Rumors are swirling Sprint will begin selling Apple’s iconic iPhone this October, bringing the number of carriers supporting the wildly popular phone to three.  Sprint shares soared 10 percent on the news.  But while Sprint customers and shareholders are celebrating the potential imminent arrival of iPhone, launching the phone on the Sprint network is no simple matter, especially for the last remaining carrier delivering truly unlimited data.

On the Plus Side

Apple’s iPhone has become a must-have for a significant number of consumers.  They won’t leave the phone behind to switch carriers, not even for Verizon Wireless, until they introduced the phone earlier this year.  Now Sprint can win its own share of iPhone devotees.

Sprint’s iPhone promotions could draw customers away from larger carriers, especially enticed by Sprint’s worry-free unlimited data plan that has become extinct at other wireless companies.

The iPhone locks customers into new two-year contracts with Sprint, helpful security at a time when AT&T threatens to further consolidate the wireless industry in its efforts to acquire T-Mobile.

On the Down Side

Sprint’s phone subsidy expenses will skyrocket with Apple’s iPhone, which commands the highest subsidies in the industry.  Analysts suspect AT&T currently shells out up to $425 for iPhone 4 and $375 for iPhone 3GS.  Then AT&T sells the phone to consumers for $200 or less, making the subsidy back over the life of the two year contract.  That hits AT&T’s cash on hand hard.  For Sprint, regularly accused by Wall Street of spending too much on customer promotions, it will only increase those costs.  Sprint pays less than $150 for its top of the line Evo phones in comparison.

One guarantee the iPhone always delivers: Lots of data hungry users.  The introduction of the iPhone may ultimately threaten Sprint’s unlimited usage experience because of demand placed on an already burdened 3G network.  There is also no guarantee the first Sprint iPhone will support Sprint’s 4G network.
