Much has been written about Sprint Nextel Corp.'s (NYSE: S) follies in recent quarters. The third-largest wireless carrier in the U.S. has lost millions of customers to larger and more successful competitors like Verizon Wireless and AT&T, Inc. (NYSE: T). But, with the launch of an extremely successful iPhone competitor (among other things), the company is showing signs of stemming its huge customer defections from past quarters.

The word of support initially came from Verizon Wireless President Denny Strigl , who told investors that Sprint's performance had picked up in the last months -- although Verizon still didn't consider Sprint to be a threat to Verizon Wireless' current results. Still, any improvement for Sprint is a good thing. Sprint CEO Dan Hesse, a wireless industry veteran with a largely successful track record, is the right person to be leading Sprint as well. So, are all the cards lined up for Sprint to become a resurgent force in the U.S. wireless industry?

It's stock has rebounded in a decent way, closing up from mid-March's $6/share to $8.91 recently (it closed yesterday at $8.94/share). Although Sprint lost over a million customers in the first quarter of 2008, the numbers should not be that bad in the second quarter. Sprint also won't be sold any time soon. Verizon Wireless, which just bought Alltel from its private owners, is the only company that could have made a merger work in buying Sprint Nextel. It would be disastrous to have another company come in and try to emulate what Sprint attempted with Nextel back in 2005, which has turned out to be a complete disaster and has led to tens of billions in write-offs (do you hear me now, Deutsche Telekom?).

Sprint has the chops to turn itself around in 2009 with some solid management and good decisions, but it still won't be easy. Spinning off the Nextel network (oops, I mean selling the spectrum off) and migrating all those customers to Sprint's network -- along with heavy retention incentives -- may be Hesse's biggest bet yet. That is, if he has the cahones to do it.
